1. Introduction
-
This document defines a number of changes and extensions to the Policy Core Lightweight Directory Access Protocol (LDAP) Schema [PCLS] based on the model extensions defined by the Policy Core Information Model (PCIM) Extensions [PCIM_EXT]. These changes and extensions consist of new LDAP object classes and attribute types [LDAP]. Some of the schema items defined in this document re- implement existing concepts in accordance with their new semantics introduced by [PCIM_EXT]. The other schema items implement new concepts, not covered by [PCLS]. This document updates RFC 3703 [PCLS].
In addition to the concepts defined by [PCIM_EXT], this document introduces two new classes: pcelsVendorVariableAuxClass and pcelsVendorValueAuxClass. These classes provide a standard extension mechanism for vendor-specific policy variables and policy values that have not been specifically modeled.
Within the context of this document, the term "PCELS" (Policy Core Extension LDAP Schema) is used to refer to the LDAP object class, attribute type definitions and the associated recommendations contained in this document.
1.1. Specification of Requirements
-
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [KEYWORDS].
2. Relationship to Other Policy Framework Documents
-
This document contains an LDAP schema mapping for the classes defined in the "Policy Core Information Model (PCIM) Extensions" [PCIM_EXT]. The LDAP schema defined in this document is an extension to the "Policy Core Lightweight Directory Access Protocol (LDAP) Schema" [PCLS], which defines the mapping of the "Policy Core Information Model -- Version 1 Specification" [PCIM] to an LDAP schema.
These three documents ([PCIM], [PCIM_EXT] and [PCLS]) are prerequisites for reading and understanding this document.
Other documents may subsequently be produced with mappings of the same model to other storage or transport technologies.
3. Inheritance Hierarchy for PCELS
-
The object class and attribute type names defined in this document are prefixed 'pcels'.
The diagram below illustrates the combined class hierarchy for the LDAP object classes defined in the following documents:
- The class names prefixed 'pcels' are defined in this document. - The class names prefixed 'pcim' are defined in [PCLS].
- The class names prefixed 'dlm1' are defined in [CIM_LDAP]. - The class named 'top' is defined in [LDAP_SCHEMA].All the new object classes except for pcelsVendorVariableAuxClass and pcelsVendorValueAuxClass, are mapped from concepts defined or modified by [PCIM_EXT]. The pcelsVendorVariableAuxClass and pcelsVendorValueAuxClass classes are not mapped from [PCIM_EXT]. They represent concepts introduced in this document.

4. General Discussion of Mapping the Policy Core Information Model
Extensions to LDAP
-
The object classes described in this document contain certain optimizations for a directory that uses LDAP as its access protocol. An example is the use of auxiliary class attachment to LDAP entries for the realization of some of the associations defined in the information model. For instance, the aggregation of a specific SimplePolicyCondition to a reusable PolicyRule [PCIM_EXT] may be realized by attaching a pcelsSimpleConditionAuxClass to a pcelsRuleInstance entry.
Note that other data stores might need to implement the associations differently.
4.1. Summary of Class Mappings
-
The classes and their properties defined in the information model [PCIM_EXT] map directly to LDAP object classes and attribute types.
The details of this mapping are discussed case by case in section 5.

Figure 2. Mapping of Information Model Extension Classes to LDAP
The pcelsVendorVariableAuxClass and pcelsVendorValueAuxClass classes are not mapped from [PCIM_EXT]. These classes are introduced in this document as a new extension mechanism for vendor-specific policy variables and values that have not been specifically modeled. Just like for any other schema elements defined in this document or in
[PCLS], a particular submodel schema generally will not need to use vendor specific variable and value classes. Submodel schemas SHOULD apply the recommendations of section 5.10 of [PCIM_EXT] with regards to the supported and unsupported elements.
-
4.2. Summary of Association Mappings
-
The associations in the information model map to one or more of the following options:
1. Attributes that reference DNs (Distinguished Names) 2. Directory Information Tree (DIT) containment (i.e., superior-subordinate relationships) in LDAP 3. Auxiliary class attachment 4. Association object classes and attributes that reference DNsThe details of this mapping are discussed case by case in section 5.

Figure 3. Mapping of Information Model Extension Associations to LDAP
Two [PCIM_EXT] associations are mapped to DIT containment:
- PolicyRoleCollectionInSystem is a weak association and weak associations map well to DIT containment [CIM_LDAP] (without being limited to this mapping). In the absence of additional constraints, DIT containment is chosen here as the optimal association mapping.
- ReusablePolicy is mapped to DIT containment for scalability reasons. It is expected that applications will associate a large number of policy instances to a ReusablePolicyContainer and DIT containment is a type of association that scales well.
4.3. Summary of Changes since PCLS
-
This section provides an overview of the changes relative to [PCLS] defined in this document:
- The concept of a set of policies is introduced by two new object classes: pcelsPolicySet and pcelsPolicySetAssociation. These classes enable the aggregation and relative prioritization of policies (rules and/or groups). The attribute pcelsPriority is used by pcelsPolicySetAssociation instances to indicate the priority of a policy relative to the other policies aggregated by the same set. Applications may use this attribute to apply appropriate ordering to the aggregated policies. This new policy aggregation mechanism provides an alternative to the aggregation mechanism defined by [PCLS] (that defines pcimRuleContainmentAuxClass and/or pcimGroupContainmentAuxClass for attaching components to a pcimGroup).
- The attribute pcimRoles defined by [PCLS] is used here by the pcelsPolicySet object class. Thus, the role based policy selection mechanism is extended to all the subclasses of pcelsPolicySet.
- A new attribute pcelsDecisionStrategy is added on the pcelsPolicySet class as a mapping from the decision mechanism.
- A new class pcelsGroup (with two subclasses), implements the modified semantics of the PolicyGroup in accordance with [PCIM_EXT]. This new class inherits from its superclass pcelsPolicySet the ability to aggregate (with relative priority) other policy rules or groups.
- A new class pcelsRule (with two subclasses), implements the modified semantics of the PolicyRule in accordance with [PCIM_EXT]. It does not include an absolute priority attribute, but instances of non-abstract subclasses of pcelsRule can be prioritized relative to each other within a System (behavior inherited from its superclass: pcelsPolicySet). The pcelsRule class also inherits from pcelsPolicySet the ability to aggregate other policy rules or groups, and thus, the ability to construct nested rule structures of arbitrary complexity.
- A new attribute pcelsExecutionStrategy is added to the pcelsRule and pcelsCompoundActionAuxClass classes to allow the specification of the expected behavior in case of multiple actions aggregated by a rule or by a compound action.
- Compound Conditions: The pcelsCompoundConditionAuxClass class is added in order to map the CompoundPolicyCondition class. A new class, pcelsConditionAssociation is used to aggregate policy conditions in a pcelsCompoundConditionAuxClass. The same class is also used to aggregate policy conditions in a pcelsRule.
- Compound Actions: The pcelsCompoundActionAuxClass class is added in order to map the CompoundPolicyAction class. A new class, pcelsActionAssociation is used to aggregate policy actions in a pcelsCompoundActionAuxClass. The same class is also used to aggregate policy actions in a pcelsRule.
9. Simple Conditions, Simple Actions, Variables and Values: The simple condition, simple action, variable and value classes defined by [PCIM_EXT] are directly mapped to LDAP object classes. These are: pcelsSimpleConditionAuxClass, pcelsSimpleActionAuxClass, pcelsVariable and its subclasses, and pcelsValueAuxClass and its subclasses.- A general extension mechanism is introduced for representing policy variables and values that have not been specifically modeled. The mechanism is intended for vendor-specific extensions.
- Reusable Policy Repository: A new class (with two subclasses), pcelsReusableContainer is created as a subclass of pcimRepository. While maintaining compatibility with older [PCLS] implementations, the addition of this class acknowledges the intent of [PCIM_EXT] to avoid the potential for confusion with the Policy Framework component named Policy Repository. The new class enables many-to-many associations between reusable policy containers.
- The ReusablePolicy association defined in [PCIM_EXT] is realized through subordination to an instance of a non-abstract subclass of pcelsReusableContainer. Thus, reusable policy components
-
(groups, rules, conditions, actions, variables and values) may be defined as stand-alone entries or stand-alone groups of related entries subordinated (DIT contained) to a pcelsReusableContainer.
- Device level filter classes are added to the schema.
- The pcelsRoleCollection class is added to the schema to allow the association of policy roles to resources represented as LDAP entries.
4.4. Relationship to PCLS Classes
-
Several [PCLS] classes are used in this document to derive other classes. If a PCELS application requires a functionality provided by any of derived classes, then the [PCLS] class MUST also be supported by PCELS implementations. These classes are:
pcimPolicy
pcimRuleConditionAssociation
pcimRuleActionAssociation
pcimConditionAuxClass
pcimActionAuxClass
pcimRepositoryOther [PCLS] classes are neither derived to nor superseded by classes defined in this document. If a PCELS application requires a functionality provided by any of these classes, then the [PCLS] class SHOULD be used. These classes are:
pcimRuleValidityAssociation
pcimTPCAuxClass
pcimConditionVendorAuxClass
pcimActionVendorAuxClass
pcimPolicyInstance
pcimElementAuxClass
pcimSubtreesPtrAuxClassAmong the classes defined in this document some implement concepts that supersede the concepts implemented by similar [PCLS] classes. PCELS implementations MAY support such [PCLS] classes. These classes are:
pcimGroup and its subclasses
pcimRule and its subclasses
pcimGroupContainmentAuxClass
pcimRuleContainmentAuxClass
the subclasses of pcimRepository
4.5. Impact on Existing Implementations of the Policy Core LDAP Schema
-
In general, the intent of PCELS is to extend the functionality offered by the Policy Core LDAP Schema. For the most part, the compatibility with [PCLS] is preserved. The few cases in which compatibility cannot be achieved due to fundamental changes imposed by [PCIM_EXT], are defined here as alternatives to the original implementation.
PCELS does not obsolete nor deprecate the concepts implemented by [PCLS]. The new LDAP schema items are defined in this document in a way that avoids, to the extent possible, interference with the normal operation of a reasonably well-executed implementation of [PCLS]. The intent is to permit at least a harmless coexistence of the two models in the same data repository.
However, it should be noted that the PCELS introduces the following changes that may have an impact on some [PCLS] implementations:
- Some attributes originally used only by pcimRule or pcimGroup are now also used by classes unknown to [PCLS] implementations (pcelsPolicySet, pcelsRule and pcelsGroup). In particular, the attribute pcimRoles is also used by pcelsPolicySet for role based policy selection.
- Condition and action association classes originally used by only pcimRule are now used (through subclasses) by pcelsRule as well.
- pcimRepository containers may include entries of types unknown to [PCLS] implementations.
When the choice exists, PCELS implementations SHOULD support the new schema and MAY also support the one defined by [PCLS]. For example, if PolicyRule support is required, an implementation SHOULD be able to read or read-write (as applicable) pcelsRule entries. The same implementation MAY be able to read or read-write pcimRule.
4.6. The Association of PolicyVariable and PolicyValues
to PolicySimpleCondition and PolicySimpleAction
-
A PolicySimpleCondition, as well as a PolicySimpleAction, includes a single PolicyValue and a single PolicyVariable. Each of them can be attached or referenced by a DN.
The attachment helps create compact PolicyCondition and PolicyAction definitions that can be efficiently provisioned and retrieved from the repository. On the other hand, referenced PolicyVariables and PolicyValues instances can be reused in the construction of multiple policies and permit an administrative partitioning of the data and policy definitions.
4.7. The Aggregation of PolicyRules and PolicyGroups in PolicySets
-
In [PCIM_EXT], the two aggregations PolicyGroupInPolicyGroup and PolicyRuleInPolicyGroup, are combined into a single aggregation PolicySetComponent. This aggregation and the capability of association between a policy and the ReusablePolicyContainer offer new possibilities of reusability. Furthermore, these aggregations introduce new semantics representing the execution of one PolicyRule within the scope of another PolicyRule.
Since PolicySet is defined in [PCIM_EXT], it is mapped in this document to a new class pcelsPolicySet in order to provide an abstraction for a set of policy rules or groups. The aggregation class PolicySetComponent in [PCIM_EXT] is mapped to a multi-value attribute pcelsPolicySetList in the pcelsPolicySet class and the attribute pcelsPolicySetDN in the pcelsPolicySetAssociation. These attributes refer to the nested rules and groups.
It is possible to store a rule/group nested in another rule/group in two ways. The first way is to define the nested rule/group as specific to the nesting rule/group. The second way is to define the nested rules/groups as reusable.
First case: Specific nested sets (rules/groups).
+----------+ |Rule/Group| | | +-----|- -|-----+ | +----------+ | | * * | | * * | | **** **** | | * * | v * * v +-----------+ +-----------+ | SA1+Set1 | | SA2+Set2 | +-----------+ +-----------+ +------------------------------+ |LEGEND: | | ***** DIT containment | | + auxiliary attachment | | ----> DN reference | +------------------------------+#: Number.
Set#: pcelsRuleAuxClass or pcelsGroupAuxClass auxiliary class. SA#: pcelsPolicySetAssocation structural class.Figure 4. Policy Set with Specific Components
The nesting pcelsPolicySet refers to instances of pcelsPolicySetAssociation using the attribute pcelsPolicySetList. These structural association classes are subordinated (DIT contained) to an instance of a non-abstract subclass of pcelsPolicySet and represent the association between the PolicySet and its nested rules/groups. The nested instances of auxiliary subclasses of pcelsPolicySet are attached to the association entries.
Second case: Reusable nested sets (rules/groups).

SA#: PolicySetAssocation structural class.
S#: structural class.Figure 5. Policy Set with Reusable Components
The nesting pcelsPolicySet refers to instances of pcelsPolicySetAssociation using the attribute pcelsPolicySetList. These structural association classes are subordinated (DIT contained) to an instance of a non-abstract subclass of pcelsPolicySet and represent the association between the PolicySet and its nested rules/groups. The reusable rules/groups are instantiated here as auxiliary classes and attached to pcimPolicyInstance entries in the reusable container. Another option is to use the structural subclasses for defining reusable rules/groups. The association classes belonging to a nesting policy set are reference the reusable rules/groups using the attribute pcelsPolicySetDN.
A combination of both specific and reusable components is also allowed for the same policy set.
4.8. The Aggregation of Actions/Conditions in PolicyRules and
CompoundActions/CompoundConditions
-
[PCIM_EXT] defines two new classes that allow the designer to create more complex conditions and actions. CompoundPolicyCondition and CompoundPolicyAction classes are mapped in this document to pcelsCompoundConditionAuxClass and pcelsCompoundActionAuxClass classes that are subclasses of pcimConditionAuxClass/pcimActionAuxClass. The compound conditions/actions defined in [PCIM_EXT] extend the capability of the rule to associate, group and evaluate conditions or execute actions. The conditions/actions are associated to compounds conditions/actions in the same way as they are associated to the rules.
In this section, how to store instances of these classes in an LDAP Directory is explained. As a general rule, specific conditions/actions are subordinated (DIT contained) to the rule or compound condition/action that aggregates them and are attached to association class instances. Reusable conditions/actions are subordinated to pcelsReusableContainer instances and attached to pcimPolicyInstance instances.
The examples below illustrate the four possible cases combining specific/reusable compound/non-compound condition/action. The rule has two compound conditions, each one has two different conditions. The schemes can be extended in order to store actions.
The examples below are based on and extend those illustrated in the section 4.4 of [PCLS].
First case:
-

-
Specific compound condition/action with specific conditions/actions.

CA#: pcelsConditionAssociation structural class. cc#: pcelsCompoundConditionAuxClass auxiliary class. c#: subclass of pcimConditionAuxClass.Figure 6. Specific Compound Conditions with Specific Components
Because the compound conditions/actions are specific to the Rule, They are auxiliary attachments to instances of the structural classes pcelsConditionAssociation or pcelsActionAssociation. These structural classes represent the association between the rule and the compound condition/action. The rule specific conditions/actions are therefore subordinated (DIT contained) to the rule entry.
The conditions/actions are tied to the compound conditions/actions in the same way the compound conditions/actions are tied to rules. Association classes realize the association between the aggregating compound conditions/actions and the specific conditions/actions.
Second case:
-
-
-
Rule specific compound conditions/actions with reusable conditions/actions.

Figure 7. Specific Compound Conditions with Reusable Components
This case is similar to the first one. The conditions/actions are reusable and are therefore not attached to the association classes, but rather to structural classes in the reusable container. The association classes tie the conditions/actions in located in a reusable container to their aggregators using DN references.
Third case:
-
-
-
Reusable compound condition/action with specific conditions/actions.

Figure 8. Reusable Compound Conditions with Specific Components
Re-usable compound conditions/actions are attached to structural classes and stored in a reusable policy container. They are related to the rule through a DN reference attribute in the association classes.
Specific conditions/actions are attached to association entries and subordinated (DIT contained) to the aggregating compound conditions/actions.
Fourth case:

Reusable conditions/actions and compound conditions/actions.

Figure 9. Reusable Compound Conditions with Reusable Components
All the conditions/actions are reusable so they are stored in reusable containers. The figure above illustrates two different reusable policy containers, but the number of containers in the system is decided based on administrative reasons. The conditions, actions, etc. may be stored in the same or different containers with no impact on the policy definition semantics.
5. Class Definitions
-
The semantics for the policy information classes that are to be mapped directly from the information model to an LDAP representation are detailed in [PCIM_EXT]. Consequently, this document presents only a brief reference to those semantics. The focus here is on the mapping from the information model (which is independent of repository type and access protocol) to a form that can be accessed using LDAP. For various reasons including LDAP specific optimization, this mapping is not always 1:1. Some new classes and attributes (that were not part of [PCIM] or [PCIM_EXT]) needed to be created in order to implement the LDAP mapping. These new LDAP-only classes are fully defined in this document.
The following notes apply to this section in its entirety.
Note 1: The formal language for specifying the classes, attributes, and DIT structure and content rules is that defined in [LDAP_SYNTAX]. In the following definitions, the class and attribute definitions follow [LDAP_SYNTAX] but they are line-wrapped to enhance human readability.
Note 2: Even though not explicitly noted in the following class and attribute definitions, implementations may define DIT structure and content rules where applicable and supported by the underlying LDAP infrastructure. In such cases, the DIT structure rule considerations discussed in section 5 of [PCLS] must be applied to PCELS implementations as well. The reasons and details are presented in [X.501].
Note 3: Wherever possible, an equality, a substrings and an ordering matching rule are defined for a particular attribute. This provides additional implementation flexibility. However, in some cases, the LDAP matching semantics may not cover all the application needs. For instance, different values of pcelsIPv4AddrList may be semantically equivalent. The equality matching rule, caseIgnoreMatch, associated to this attribute type is not suitable for detecting this equivalence. Implementers should not rely solely on LDAP syntaxes and matching rules for being consistent with this specification.
Note 4: The following attribute definitions use only LDAP matching rules and syntax definitions from [LDAP_SYNTAX], [LDAP_SCHEMA] and [LDAP_MATCH]. The corresponding X.500 matching rules are defined in [X.520].
Note 5: Some of the following attribute types MUST conform to additional constraints on various data types (e.g., the only valid values for pcelsDecisionStrategy are 1 and 2). Just like the attribute semantics, the definition of the value structures, valid ranges, etc. is covered by [PCIM_EXT] for the corresponding properties while such constraints are only briefly mentioned in this document. In all cases, if a constraint is violated, the entry SHOULD be treated as invalid and the policy rules or groups that refer to it SHOULD be treated as being disabled, meaning that the execution of such policy rules or groups SHOULD be stopped.
Note 6: Some of the object classes defined in this section cannot or should not be directly instantiated because they are either defined as abstract or do not implement stand-alone semantics (e.g., pcelsValueAuxClass). Regarding instances of objects that inherit from such classes, the text refers to "instances of <class_name>" when in fact the strictly correct expression would be "instances of objects that belong to non-abstract subclasses of <class_name>". The omission is intentional; it makes the text easier to read.
5.1. The Abstract Class pcelsPolicySet
-
The pcelsPolicySet class represents a set of policies with a common decision strategy and a common set of policy roles. This class together with the pcelsPolicySetAssociation class defined in a subsequent section of this document provide sufficient information to allow applications to apply appropriate ordering to a set of policies. The pcelsPolicySet is mapped from the PolicySet class [PCIM_EXT]. The pcelsPolicySet class is an abstract object class and it is derived from the pcimPolicy class [PCLS].
The pcelsPolicySetList attribute of a pcelsPolicySet instance references subordinated pcelsPolicySetAssociation entries. The aggregated pcelsPolicySet instances are either attached to the pcelsPolicySetAssociation entries as auxiliary object classes or referenced by the pcelsPolicySetAssociation entries using the pcelsPolicySetDN attribute.
The pcelsPolicySet class is defined as follows:
( 1.3.6.1.1.9.1.1 NAME 'pcelsPolicySet' DESC 'Set of policies' SUP pcimPolicy ABSTRACT MAY ( pcelsPolicySetName $ pcelsDecisionStrategy $ pcimRoles $ pcelsPolicySetList ) )One of the attributes of the pcelsPolicySet class, pcimRoles is defined in the section 5.3 of [PCLS]. In the pcelsPolicySet class the pcimRole attribute preserves its syntax and semantics as defined by [PCLS] and [PCIM].
The pcelsPolicySetName attribute type may be used as naming attribute for pcelsPolicySet entries. This attribute type is of syntax Directory String [LDAP_SYNTAX]. It has an equality matching rule of caseIgnoreMatch, an ordering matching rule of caseIgnoreOrderingMatch and a substrings matching rule of caseIgnoreSubstringsMatch [LDAP_SYNTAX]. Attributes of this type can only have a single value.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.1 NAME 'pcelsPolicySetName' DESC 'User-friendly name of a policy set' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE )The pcelsDecisionStrategy attribute type indicates the evaluation method for the policies aggregated in the policy set. It is mapped from the PolicySet.PolicyDecisionStrategy property [PCIM_EXT]. This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH]. Attributes of this type can only have a single value. The only allowed values for attributes of this type are 1 (FirstMatching) and 2 (AllMatching). If this attribute is missing from a pcelsPolicySet instance, applications MUST assume a FirstMatching decision strategy for the policy set.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.2 NAME 'pcelsDecisionStrategy' DESC 'Evaluation method for the components of a pcelsPolicySet' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )The pcelsPolicySetList attribute type is used in the realization of the PolicySetComponent association [PCIM_EXT]. This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can have multiple values. The only allowed values for pcelsPolicySetList attributes are DNs of pcelsPolicySetAssociation entries. In a pcelsPolicySet, the pcelsPolicySetList attribute represents the associations between this policy set and its components.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.3 NAME 'pcelsPolicySetList' DESC 'Unordered set of DNs of pcelsPolicySetAssociation entries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )Note: A pcelsPolicySet instance aggregates other pcelsPolicySet instances using pcelsPolicySetAssociation entries (defined in the next section). Applications can sort the components of a pcelsPolicySet using attributes of the pcelsPolicySetAssociation entries. However, implementations should not expect the LDAP data store to provide a useful ordering of the pcelsPolicySetList values in a pcelsPolicySet instance or to return sets of matching pcelsPolicySetAssociation entries in a meaningful order. Instead, applications SHOULD implement their own means for post-retrieval ordering of policy rules/groups based on pcelsPolicySetAssociation.pcelsPriority values.
5.2. The Structural Class pcelsPolicySetAssociation
-
The pcelsPolicySetAssociation class is used to associate PolicySet instances [PCIM_EXT] to other entries. pcelsPolicySetAssociation entries are always subordinated to the aggregating entry. When subordinated to an instance of pcelsPolicySet, pcelsPolicySetAssociation realizes a PolicySetComponent association [PCIM_EXT]. When subordinated to an instance of dlm1System [CIM_LDAP], pcelsPolicySetAssociation realizes a PolicySetInSystem association [PCIM_EXT].
The pcelsPolicySetAssociation class is a structural object class and it is derived from the pcimPolicy class [PCLS].
The aggregation of a reusable pcelsPolicySet instance is realized via the pcelsPolicySetDN attribute. A non-reusable pcelsPolicySet instance is attached (as auxiliary subclass of pcelsPolicySet) directly to the pcelsPolicySetAssociation entry.
When reading a pcelsPolicySetAssociation instance that has a pcelsPolicySet attached, the attribute pcelsPolicySetDN MUST be ignored. Applications SHOULD remove the pcelsPolicySetDN value from a pcelsPolicySetAssociation upon attachment of a pcelsPolicySet to the entry.
The pcelsPolicySetAssociation class is defined as follows:
( 1.3.6.1.1.9.1.2 NAME 'pcelsPolicySetAssociation' DESC 'Associates a policy set to an aggregating entry' SUP pcimPolicy STRUCTURAL MUST ( pcelsPriority ) MAY ( pcelsPolicySetName $ pcelsPolicySetDN ) )The pcelsPriority attribute type indicates the priority of a policy set component. This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH]. Attributes of this type can only have single values. The only allowed values for attributes of this type are non-negative integers. Within the set of pcelsPolicySetAssociation entries directly subordinated to a pcelsPolicySet or a dlm1System [CIM_LDAP], the pcelsPriority values MUST be unique.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.4 NAME 'pcelsPriority' DESC 'Priority of a component' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )The pcelsPolicySetDN attribute type is used in the aggregation of PolicySet instances [PCIM_EXT]. This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can only have single values. The only allowed values for pcelsPolicySetDN attributes are DNs of pcelsPolicySet entries.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.5 NAME 'pcelsPolicySetDN' DESC 'DN of a pcelsPolicySet entry' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 SINGLE-VALUE )
5.3. The Three Policy Group Classes
-
The pcelsGroup class is the base class for representing a policy group. It is mapped from the modified PolicyGroup class [PCIM_EXT]. The pcelsGroup class is derived from the pcelsPolicySet class. To maximize flexibility, the pcelsGroup class is defined as abstract. An auxiliary subclass pcelsGroupAuxClass enables the attachment of a policy group to an existing entry, while a structural subclass pcelsGroupInstance permits the representation of a policy group as a standalone entry.
The pcelsGroup class is defined as follows:
( 1.3.6.1.1.9.1.3 NAME 'pcelsGroup' DESC 'Base class for representing a policy group' SUP pcelsPolicySet ABSTRACT MAY ( pcimGroupName ) )The pcelsGroupAuxClass class is defined as follows:
( 1.3.6.1.1.9.1.4 NAME 'pcelsGroupAuxClass' DESC 'Auxiliary class for representing a policy group' SUP pcelsGroup AUXILIARY )The pcelsGroupInstance class is defined as follows:
( 1.3.6.1.1.9.1.5 NAME 'pcelsGroupInstance' DESC 'Structural class for representing a policy group' SUP pcelsGroup STRUCTURAL )The pcimGroupName attribute type used by the pcelsGroup class is defined in the section 5.2 of [PCLS]. In the pcelsGroup object class, this attribute preserves its syntax and semantics as defined by [PCLS] and [PCIM].
Note: PCELS implementations SHOULD support pcelsGroup and its two subclasses and MAY also support pcimGroup and its two subclasses [PCLS]. Applications that choose to support pcelsGroup and its two subclasses MUST use the aggregation mechanism provided by pcelsPolicySetAssociation for aggregating policy groups or policy rules in policy groups represented as instances of pcelsGroup.
5.4. The Three Policy Rule Classes
-
The pcelsRule class is the base class for representing a policy rule. It is mapped from the modified PolicyRule class [PCIM_EXT]. The pcelsRule class is derived from the pcelsPolicySet class. To maximize flexibility, the pcelsRule class is defined as abstract. An auxiliary subclass pcelsRuleAuxClass enables the attachment of a policy rule to an existing entry, while a structural subclass pcelsRuleInstance permits the representation of a policy rule as a standalone entry.
When reading a pcelsRule instance that has a pcimConditionAuxClass attached, from the policy rule perspective the attribute pcelsConditionList MUST be ignored. For example, if present, the attribute MUST NOT be considered an association between this policy rule and a policy condition. Such situations may occur, for example, when a pcelsCompoundConditionAuxClass is attached to a pcelsRule instance.
When reading a pcelsRule instance that has a pcimActionAuxClass attached, from the policy rule perspective the attribute pcelsActionList MUST be ignored. For example, if present, the attribute MUST NOT be considered an association between this policy rule and a policy action. Such situations may occur, for example, when a pcelsCompoundActionAuxClass is attached to a pcelsRule instance.
The pcelsRule class is defined as follows:
( 1.3.6.1.1.9.1.6 NAME 'pcelsRule' DESC 'Base class for representing a policy rule' SUP pcelsPolicySet ABSTRACT MAY ( pcimRuleName $ pcimRuleEnabled $ pcimRuleUsage $ pcimRuleMandatory $ pcelsRuleValidityPeriodList $ pcelsConditionListType $ pcelsConditionList $ pcelsActionList $ pcelsSequencedActions $ pcelsExecutionStrategy ) )The pcelsRuleAuxClass class is defined as follows:
( 1.3.6.1.1.9.1.7 NAME 'pcelsRuleAuxClass' DESC 'Auxiliary class for representing a policy rule' SUP pcelsRule AUXILIARY )The pcelsRuleInstance class is defined as follows:
( 1.3.6.1.1.9.1.8 NAME 'pcelsRuleInstance' DESC 'Structural class for representing a policy rule' SUP pcelsRule STRUCTURAL )Four of the attributes used by the pcelsRule class are defined in the section 5.3 of [PCLS]. These attributes are: pcimRuleName, pcimRuleEnabled, pcimRuleUsage and pcimRuleMandatory. In the pcelsRule object class, these attributes preserve their syntax and semantics as defined by [PCLS] and [PCIM].
The attributes pcimRuleValidityPeriodList, pcimRuleConditionListType, pcimRuleConditionList, pcimRuleActionList and pcimRuleSequencedActions defined in [PCLS] are not used by pcelsRule. Instead, this class uses the new attributes pcelsRuleValidityPeriodList, pcelsConditionListType, pcelsConditionList, pcelsActionList and pcelsSequencedActions. Except for pcelsRuleValidityPeriodList, the new attributes are also used for similar purpose by either pcelsCompoundConditionAuxClass or pcelsCompoundActionAuxClass.
The pcelsRuleValidityPeriodList attribute type is used in the realization of the PolicyRuleValidityPeriod association ([PCIM_EXT] and [PCIM]). This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can have multiple values. The only allowed values for pcelsRuleValidityPeriodList attributes are DNs of pcimRuleValidityAssociation entries. In a pcelsRule, the pcelsRuleValidityPeriodList attribute represents the associations between this policy rule and its time period conditions.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.62 NAME 'pcelsRuleValidityPeriodList' DESC 'Unordered set of DNs of pcimRuleValidityAssociation entries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )The pcelsConditionListType attribute type indicates whether the set of aggregated conditions is in disjunctive or conjunctive normal form. It is mapped from the PolicyRule.ConditionListType property [PCIM] (identical to the CompoundPolicyCondition.ConditionListType property defined in [PCIM_EXT]). This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH]. Attributes of this type can only have a single value. The only allowed values for attributes of this type are 1 (Disjunctive) and 2 (Conjunctive). If this attribute is missing from a pcelsRule instance, applications MUST assume that the set of aggregated conditions is in disjunctive normal form.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.6 NAME 'pcelsConditionListType' DESC 'Indicates the type of condition aggregation' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )The pcelsConditionList attribute type is used in the realization of the PolicyConditionStructure association [PCIM_EXT]. This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can have multiple values. The only allowed values for pcelsConditionList attributes are DNs of pcelsConditionAssociation entries. In a pcelsRule, the pcelsConditionList attribute represents the associations between this policy rule and its conditions.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.7 NAME 'pcelsConditionList' DESC 'Unordered set of DNs of pcelsConditionAssociation entries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )The pcelsActionList attribute type is used in the realization of the PolicyActionStructure association [PCIM_EXT]. This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can have multiple values. The only allowed values for pcelsActionList attributes are DNs of pcelsActionAssociation entries. In a pcelsRule, the pcelsActionList attribute represents the associations between this policy rule and its actions.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.8 NAME 'pcelsActionList' DESC 'Unordered set of DNs of pcelsActionAssociation entries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )The pcelsSequencedActions attribute type indicates whether the ordered execution of actions in an aggregate is Mandatory, Recommended or DontCare. It is mapped from the PolicyRule.SequencedActions property [PCIM] (identical to the CompoundPolicyAction.SequencedActions property defined in [PCIM_EXT]). This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH]. Attributes of this type can only have a single value. The only allowed values for attributes of this type are 1 (Mandatory), 2 (Recommended) and 3 (DontCare). If this attribute is missing from a pcelsRule instance, applications MUST assume that the ordered execution of actions in this rule is not important (DontCare).
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.9 NAME 'pcelsSequencedActions' DESC 'Indicates the importance of action sequencing' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )The pcelsExecutionStrategy attribute type indicates whether the actions in an aggregate are to be executed until success, all (independent of their outcome) or until failure. It is mapped from the PolicyRule.ExecutionStrategy property [PCIM_EXT] (identical to the CompoundPolicyAction.ExecutionStrategy property). This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH]. Attributes of this type can only have a single value. The only allowed values for attributes of this type are 1 (Do until success), 2 (Do all) and 3 (Do until failure). If this attribute is missing from a pcelsRule instance, applications MUST assume that all the actions are to be executed (Do all).
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.10 NAME 'pcelsExecutionStrategy' DESC 'Indicates the action execution strategy' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )Note 1: Rule validity periods for an instance of pcelsRule are realized using the attribute pcelsRuleValidityPeriodList and pcimRuleValidityAssociation [PCLS] entries subordinated to the rule.
If DIT structure rules and name forms are written for a PCELS implementation (as suggested in section 5.5 of [PCLS]), they would require that an instance of the pcimRuleValidityAssociation class have as its superior an instance of the pcelsRule class or, if applicable, an instance of the pcimRule class. Any structure rules and name forms that require an instance of the pcimRuleValidityAssociation class to have as its superior only an instance of the pcimRule class, are in conflict and MUST be removed.
Note 2: PCELS implementations SHOULD support pcelsRule and its two subclasses and MAY also support pcimRule and its two subclasses [PCLS]. Applications that choose to support pcelsRule and its two subclasses MUST use the aggregation mechanism provided by pcelsPolicySetAssociation for aggregating policy groups or policy rules in policy rules represented as instances of pcelsRule.
5.5. The Structural Class pcelsConditionAssociation
-
The pcelsConditionAssociation class is used in the aggregation of PolicyCondition instances [PCIM]. pcelsConditionAssociation entries are always subordinated to the aggregating entry. When subordinated to an instance of pcelsRule, the pcelsConditionAssociation entry realizes the PolicyConditionInPolicyRule association [PCIM_EXT]. When subordinated to an instance of pcelsCompoundConditionAuxClass, the pcelsConditionAssociation entry realizes the PolicyConditionInPolicyCondition association [PCIM_EXT].
The pcelsConditionAssociation class is a structural object class and it is derived from the pcimRuleConditionAssociation class [PCLS].
The aggregation of a reusable instance of pcimConditionAuxClass is realized via the pcimConditionDN attribute. A non-reusable instance of pcimConditionAuxClass is attached directly to the pcelsConditionAssociation entry.
When reading a pcelsConditionAssociation entry that has a pcimConditionAuxClass instance attached, the attribute pcimConditionDN MUST be ignored. Applications SHOULD remove the pcimConditionDN value from a pcelsConditionAssociation upon attachment of a pcimConditionAuxClass to the entry.
The pcelsConditionAssociation class is defined as follows:
( 1.3.6.1.1.9.1.9 NAME 'pcelsConditionAssociation' DESC 'Associates a policy conditions to an aggregating entry' SUP pcimRuleConditionAssociation STRUCTURAL )This class extends the semantics of the pcimRuleConditionAssociation object class without using any new attributes. All its attributes are inherited from the pcimRuleConditionAssociation that is defined in section 5.4 of [PCLS].
5.6. The Structural Class pcelsActionAssociation
-
The pcelsActionAssociation class is used in the aggregation of PolicyAction instances [PCIM]. pcelsActionAssociation entries are always subordinated to the aggregating entry. When subordinated to a pcelsRule instance, the pcelsActionAssociation entry realizes the PolicyActionInPolicyRule association [PCIM_EXT]. When subordinated to an instance of pcelsCompoundActionAuxClass, the pcelsActionAssociation entry realizes the PolicyActionInPolicyAction association [PCIM_EXT].
The pcelsActionAssociation class is a structural object class and it is derived from the pcimRuleActionAssociation class [PCLS].
The aggregation of a reusable instance of pcimActionAuxClass is realized via the pcimActionDN attribute. A non-reusable instance of pcimActionAuxClass is attached directly to the pcelsActionAssociation entry.
When reading a pcelsActionAssociation entry that has a pcimActionAuxClass instance attached, the attribute pcimActionDN MUST be ignored. Applications SHOULD remove the pcimActionDN value from a pcelsActionAssociation upon attachment of a pcimActionAuxClass to the entry.
The pcelsActionAssociation class is defined as follows:
( 1.3.6.1.1.9.1.10 NAME 'pcelsActionAssociation' DESC 'Associates a policy conditions to an aggregating entry' SUP pcimRuleActionAssociation STRUCTURAL )This class extends the semantics of the pcimRuleActionAssociation object class without using any new attributes. All its attributes are inherited from the pcimRuleActionAssociation that is defined in section 5.6 of [PCLS].
5.7. The Auxiliary Class pcelsSimpleConditionAuxClass

The pcelsSimpleConditionAuxClass class implements a Value matching condition for a Variable. It is mapped from the SimplePolicyCondition class [PCIM_EXT]. The pcelsSimpleConditionAuxClass class is an auxiliary object class and it is derived from the pcimConditionAuxClass class [PCLS].
A reusable variable/value is associated to a pcelsSimpleConditionAuxClass via the pcelsVariableDN/pcelsValueDN reference from the simple condition instance. A non-reusable variable/value is associated directly as auxiliary object class to the same entry as the pcelsSimpleConditionAuxClass instance.
When reading a pcelsSimpleConditionAuxClass instance that has an instance of pcelsVariable attached, the attribute pcelsVariableDN MUST be ignored. Applications SHOULD remove the pcelsVariableDN value from a pcelsSimpleConditionAuxClass instance upon attachment of a pcelsVariable instance to the same entry.

5.18. The Three Reusable Policy Container Classes
-
The pcelsReusableContainer class represents a container of reusable policy elements. It is mapped from the ReusablePolicyContainer class [PCIM_EXT]. The pcelsReusableContainer class is derived from the pcimRepository class [PCLS]. To maximize flexibility, the pcelsReusableContainer class is defined as abstract. An auxiliary subclass pcelsReusableContainerAuxClass enables the attachment of a reusable policy container to an existing entry, while a structural subclass pcelsReusableContainerInstance permits the representation of a reusable policy container as a standalone entry.
The elements contained in a reusable policy container are aggregated via subordination to a pcelsReusableContainer instance (DIT containment). A reusable policy container can include the elements of another reusable policy container by aggregating the container itself. This is realized by DIT containment when the policy containers are subordinated to one another, or by reference when the aggregating policy container references the aggregated one using the attribute pcelsReusableContainerList.
The pcelsReusableContainer class is defined as follows:

5.21. The Structural Class pcelsIPHeadersFilter
-
The pcelsIPHeadersFilter class provides the most commonly required attributes for performing filtering on IP, TCP or UDP headers. It is mapped from the IpHeadersFilter class [PCIM_EXT]. It is a structural object class derived from the pcelsFilterEntryBase class.
The pcelsIPHeadersFilter class is defined as follows:

5.23. The Auxiliary Class pcelsFilterListAuxClass
-
The pcelsFilterListAuxClass class represents a collection of device- level filters aggregated in a policy condition. It is mapped from the FilterList class [PCIM_EXT]. pcelsFilterListAuxClass instances can be used as conditions in policy rules or as components in compound conditions. The pcelsFilterListAuxClass class is an auxiliary object class and it is derived from the pcimConditionAuxClass class [PCLS].
The pcelsFilterListAuxClass class is defined as follows:
( 1.3.6.1.1.9.1.55 NAME 'pcelsFilterListAuxClass' DESC 'Collection of pcelsFilterEntryBase filters' SUP pcimConditionAuxClass AUXILIARY MAY ( pcelsFilterListName $ pcelsFilterDirection $ pcelsFilterEntryList ) )The pcelsFilterListName attribute type may be used as naming attribute for pcelsFilterListAuxClass entries. This attribute type is of syntax Directory String [LDAP_SYNTAX]. It has an equality matching rule of caseIgnoreMatch, an ordering matching rule of caseIgnoreOrderingMatch and a substrings matching rule of caseIgnoreSubstringsMatch [LDAP_SYNTAX]. Attributes of this type can only have a single value.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.55 NAME 'pcelsFilterListName' DESC 'User-friendly name of a FilterList' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE )The pcelsFilterDirection attribute type indicates the direction of the packets or messages relative to the interface where the filter is applied. It is mapped from the FilterList.Direction property [PCIM_EXT]. This attribute type is of syntax Integer [LDAP_SYNTAX]. It has an equality matching rule of integerMatch [LDAP_SYNTAX] and an ordering matching rule of integerOrderingMatch [LDAP_MATCH].
Attributes of this type can only have a single value. The only allowed values for attributes of this type are 0 (NotApplicable), 1 (Input), 2 (Output), 3 (Both) and 4 (Mirrored). If this attribute is missing from a pcelsFilterListAuxClass instance, applications MUST assume that a direction is not applicable.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.56 NAME 'pcelsFilterDirection' DESC 'Direction to which this filter is applied' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 SINGLE-VALUE )The pcelsFilterEntryList attribute type realizes the EntriesInFilterList association [PCIM_EXT]. This attribute type is of syntax DN [LDAP_SYNTAX]. It has an equality matching rule of distinguishedNameMatch [LDAP_SYNTAX]. Attributes of this type can have multiple values. The only allowed values for pcelsFilterEntryList attributes are DNs of pcelsFilterEntryBase entries. In a pcelsFilterListAuxClass, the pcelsFilterEntryList attribute represents the associations between this filter collection and its components.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.57 NAME 'pcelsFilterEntryList' DESC 'Unordered set of DNs of pcelsFilterEntryBase entries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )The EntrySequence property of the association EntriesInFilterList is restricted to a single value ('0') [PCIM_EXT] which makes it redundant. Therefore, its mapping to an LDAP schema element is unnecessary.
5.24. The Auxiliary Class pcelsVendorVariableAuxClass
-
The pcelsVendorVariableAuxClass class provides a general extension mechanism for representing policy variables that have not been specifically modeled. Instead, its two properties are used to define the content and format of the variable, as explained below. This class is intended for vendor-specific extensions that are not amenable to using pcelsVariable; standardized extensions SHOULD NOT use this class.
The pcelsVendorVariableAuxClass class is an auxiliary object class and it is derived from the pcelsVariable class.
The pcelsVendorVariableAuxClass class is defined as follows:
( 1.3.6.1.1.9.1.56 NAME 'pcelsVendorVariableAuxClass' DESC 'Defines registered means to describe a policy variable' SUP pcelsVariable AUXILIARY MAY ( pcelsVendorVariableData $ pcelsVendorVariableEncoding ) )The pcelsVendorVariableData attribute provides a general mechanism for representing policy variables that have not been specifically modeled. This attribute type is of syntax OctetString [LDAP_SYNTAX]. It has an equality matching rule of octetStringMatch [LDAP_SCHEMA] and an ordering matching rule of octetStringOrderingMatch [LDAP_MATCH]. Attributes of this type can have multiple values. In pcelsVendorVariableAuxClass instances, the format of the values for attributes of this type is identified by the OID stored in the pcelsVendorVariableEncoding attribute.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.58 NAME 'pcelsVendorVariableData' DESC 'Mechanism for representing variables that have not been specifically modeled' EQUALITY octetStringMatch ORDERING octetStringOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )The pcelsVendorVariableEncoding attribute identifies the format for representing policy variables that have not been specifically modeled. This attribute type is of syntax OID [LDAP_SYNTAX]. It has an equality matching rule of objectIdentifierMatch [LDAP_SYNTAX]. Attributes of this type can only have a single value. In pcelsVendorVariableAuxClass instances, the pcelsVendorVariableEncoding attribute is used to identify the format and semantics for the pcelsVendorVariableData attribute values.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.59 NAME 'pcelsVendorVariableEncoding' DESC 'Identifies the format and semantics for policy variables' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 SINGLE-VALUE )
5.25. The Auxiliary Class pcelsVendorValueAuxClass
-
The pcelsVendorValueAuxClass class provides a general extension mechanism for representing policy values that have not been specifically modeled. Instead, its two properties are used to define the content and format of the policy value, as explained below. This class is intended for vendor-specific extensions that are not amenable to using pcelsValueAuxClass; standardized extensions SHOULD NOT use this class.
The pcelsVendorValueAuxClass class is an auxiliary object class and it is derived from the pcelsValueAuxClass class.
The pcelsVendorValueAuxClass class is defined as follows:
( 1.3.6.1.1.9.1.57 NAME 'pcelsVendorValueAuxClass' DESC 'Defines registered means to describe a policy value' SUP pcelsValueAuxClass AUXILIARY MAY ( pcelsVendorValueData $ pcelsVendorValueEncoding ) )The pcelsVendorValueData attribute provides a general mechanism for representing policy values that have not been specifically modeled. This attribute type is of syntax OctetString [LDAP_SYNTAX]. It has an equality matching rule of octetStringMatch [LDAP_SCHEMA] and an ordering matching rule of octetStringOrderingMatch [LDAP_MATCH]. Attributes of this type can have multiple values. In pcelsVendorValueAuxClass instances, the format of the values for attributes of this type is identified by the OID stored in the pcelsVendorValueEncoding attribute.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.60 NAME 'pcelsVendorValueData' DESC 'Mechanism for representing values that have not been specifically modeled' EQUALITY octetStringMatch ORDERING octetStringOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )The pcelsVendorValueEncoding attribute identifies the format for representing policy values that have not been specifically modeled. This attribute type is of syntax OID [LDAP_SYNTAX]. It has an equality matching rule of objectIdentifierMatch [LDAP_SYNTAX]. Attributes of this type can only have a single value. In pcelsVendorVarlueAuxClass instances, the pcelsVendorValueEncoding attribute is used to identify the format and semantics for the pcelsVendorValueData attribute values.
This attribute type is defined as follows:
( 1.3.6.1.1.9.2.61 NAME 'pcelsVendorValueEncoding' DESC 'Identifies the format and semantics for policy values' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 SINGLE-VALUE )
