Abstract

摘要

X.500 collective attributes allow common characteristics to be shared between collections of entries. This document summarizes the X.500 information model for collective attributes and describes use of collective attributes in LDAP (Lightweight Directory Access Protocol). This document provides schema definitions for collective attributes for use in LDAP.

X.500集合属性允许在条目集合之间共享公共特征。本文档总结了集合属性的X.500信息模型,并描述了集合属性在LDAP(轻量级目录访问协议)中的使用。本文档为LDAP中使用的集合属性提供模式定义。

1. Introduction
1. 介绍

In X.500 [X.500], a collective attribute is "a user attribute whose values are the same for each member of an entry collection" [X.501]. This document details their use in the Lightweight Directory Access Protocol (LDAP) [RFC3377].

在X.500[X.500]中,集合属性是“其值对于条目集合的每个成员都相同的用户属性”[X.501]。本文档详细介绍了它们在轻量级目录访问协议(LDAP)[RFC3377]中的使用。

1.1. Entry Collections
1.1. 条目集合

A collection of entries is a grouping of object and alias entries based upon common properties or shared relationship between the corresponding entries which share certain attributes. An entry collection consists of all entries within scope of a collective attributes subentry [RFC3672]. An entry can belong to several entry collections.

条目集合是基于共享某些属性的相应条目之间的公共属性或共享关系对对象和别名条目进行的分组。条目集合由集合属性子条目[RFC3672]范围内的所有条目组成。一个条目可以属于多个条目集合。

1.2. Collective Attributes
1.2. 集体属性

Attributes shared by the entries comprising an entry collection are called collective attributes. Values of collective attributes are visible but not updateable to clients accessing entries within the collection. Collective attributes are updated (i.e., modified) via their associated collective attributes subentry.

组成条目集合的条目共享的属性称为集合属性。集合属性的值对访问集合中的项的客户端可见,但不可更新。集合属性通过其关联的集合属性子项进行更新(即修改)。

When an entry belongs to multiple entry collections, the entry's values of each collective attribute are combined such that independent sources of these values are not manifested to clients.

当一个条目属于多个条目集合时,将组合每个集合属性的条目值,以便这些值的独立来源不会显示给客户端。

Entries can specifically exclude a particular collective attribute by listing the attribute as a value of the collectiveExclusions attribute. Like other user attributes, collective attributes are subject to a variety of controls including access, administrative, and content controls.

条目可以通过将特定集合属性列为CollectiveExclutions属性的值来明确排除该属性。与其他用户属性一样,集合属性受各种控制,包括访问、管理和内容控制。

1.3. Conventions
1.3. 习俗

Schema definitions are provided using LDAPv3 [RFC2251] description formats [RFC2252]. Definitions provided here are formatted (line wrapped) for readability.

使用LDAPv3[RFC2251]描述格式[RFC2252]提供模式定义。为了便于阅读,这里提供的定义是格式化的(换行)。

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 BCP 14 [RFC2119].

本文件中的关键词“必须”、“不得”、“必需”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照BCP 14[RFC2119]中所述进行解释。

2. System Schema for Collective Attributes
2. 集合属性的系统模式

The following operational attributes are used to manage Collective Attributes. LDAP servers [RFC3377] MUST act in accordance with the X.500 Directory Models [X.501] when providing this service.

以下操作属性用于管理集合属性。提供此服务时,LDAP服务器[RFC3377]必须按照X.500目录模型[X.501]操作。

2.1. collectiveAttributeSubentry
2.1. 集合属性子项

Subentries of this object class are used to administer collective attributes and are referred to as collective attribute subentries.

此对象类的子项用于管理集合属性,称为集合属性子项。

( 2.5.17.2 NAME 'collectiveAttributeSubentry' AUXILIARY )

(2.5.17.2名称“集合属性子项”辅助)

A collective attribute subentry SHOULD contain at least one collective attribute. The collective attributes contained within a collective attribute subentry are available for finding, searching, and comparison at every entry within the scope of the subentry. The collective attributes, however, are administered (e.g., modified) via the subentry.

集合属性子项应至少包含一个集合属性。集合属性子项中包含的集合属性可用于在子项范围内的每个项上查找、搜索和比较。但是,集合属性是通过子项管理(例如,修改)的。

Implementations of this specification SHOULD support collective attribute subentries in both collectiveAttributeSpecificArea (2.5.23.5) and collectiveAttributeInnerArea (2.5.23.6) administrative areas [RFC3672][X.501].

本规范的实现应支持collectiveAttributeSpecificArea(2.5.23.5)和collectiveAttributeInnerArea(2.5.23.6)管理区域[RFC3672][X.501]中的集合属性子项。

2.2. collectiveAttributeSubentries
2.2. 集合属性子项

The collectiveAttributeSubentries operational attribute identifies all collective attribute subentries that affect the entry.

CollectiveAttributesSubEntries操作属性标识影响该项的所有集合属性子项。

( 2.5.18.12 NAME 'collectiveAttributeSubentries' EQUALITY distinguishedNameMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 USAGE directoryOperation NO-USER-MODIFICATION )

(2.5.18.12名称“collectiveAttributeSubentries”相等区分名称匹配语法1.3.6.1.4.1.1466.115.121.1.12使用指南操作无用户修改)

2.3. collectiveExclusions
2.3. 集体排除

The collectiveExclusions operational attribute allows particular collective attributes to be excluded from an entry. It MAY appear in any entry and MAY have multiple values.

CollectiveExclutions操作属性允许从条目中排除特定的集合属性。它可能出现在任何条目中,并且可能有多个值。

( 2.5.18.7 NAME 'collectiveExclusions' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 USAGE directoryOperation )

(2.5.18.7名称“CollectiveExclutions”相等objectIdentifierMatch语法1.3.6.1.4.1.1466.115.121.1.38使用目录操作)

The descriptor excludeAllCollectiveAttributes is associated with the OID 2.5.18.0. When this descriptor or OID is present as a value of the collectiveExclusions attribute, all collective attributes are excluded from an entry.

描述符excludeAllCollectiveAttributes与OID 2.5.18.0相关联。当此描述符或OID作为CollectiveExclutions属性的值出现时,将从条目中排除所有集合属性。

3. Collective Attribute Types
3. 集合属性类型

A userApplications attribute type can be defined to be COLLECTIVE [RFC2252]. This indicates that the same attribute values will appear in the entries of an entry collection subject to the use of the collectiveExclusions attribute and other administrative controls. These administrative controls MAY include DIT Content Rules, if implemented.

userApplications属性类型可以定义为集合[RFC2252]。这表示在使用CollectiveExclutions属性和其他管理控件的情况下,条目集合的条目中将显示相同的属性值。如果实施,这些管理控制可能包括DIT内容规则。

Collective attribute types are commonly defined as subtypes of non-collective attribute types. By convention, collective attributes are named by prefixing the name of their non-collective supertype with "c-". For example, the collective telephone attribute is named c-TelephoneNumber after its non-collective supertype telephoneNumber.

集合属性类型通常定义为非集合属性类型的子类型。按照惯例,集合属性是通过在其非集合超类型的名称前面加上“c-”来命名的。例如,集合电话属性在其非集合超类型TelephoneNumber之后命名为c-TelephoneNumber。

Non-collective attributes types SHALL NOT subtype collective attributes.

非集合属性类型不得作为集合属性的子类型。

Collective attributes SHALL NOT be SINGLE-VALUED. Collective attribute types SHALL NOT appear in the attribute types of an object class definition.

集体属性不得为单值属性。集合属性类型不得出现在对象类定义的属性类型中。

Operational attributes SHALL NOT be defined to be collective.

操作属性不得定义为集合属性。

The remainder of section provides a summary of collective attributes derived from those defined in [X.520]. The SUPerior attribute types are described in [RFC 2256] for use with LDAP.

第节的其余部分总结了从[X.520]中定义的集合属性衍生而来的集合属性。[RFC 2256]中描述了用于LDAP的高级属性类型。

4. Security Considerations
4. 安全考虑

Collective attributes, like other attributes, are subject to access control restrictions and other administrative policy. Generally speaking, collective attributes accessed via an entry in a collection are governed by rules restricting access to attributes of that entry. And collective attributes access via a subentry are governed by rules restricting access to attributes of that subentry. However, as LDAP does not have a standard access model, the particulars of each server's access control system may differ.

集合属性与其他属性一样,受访问控制限制和其他管理策略的约束。一般来说,通过集合中的条目访问的集合属性受限制访问该条目属性的规则控制。通过子项访问的集合属性由限制访问该子项属性的规则控制。但是,由于LDAP没有标准的访问模型,因此每个服务器的访问控制系统的细节可能会有所不同。

General LDAP security considerations [RFC3377] also apply.

一般LDAP安全注意事项[RFC3377]也适用。

5. IANA Considerations
5. IANA考虑

The IANA has registered the LDAP descriptors [RFC3383] defined in this technical specification. The following registration template is suggested:

IANA已注册了本技术规范中定义的LDAP描述符[RFC3383]。建议使用以下注册模板:
