ITU-T X.520 (10/2016) v Introduction This Recommendation | Interna

33、tional Standard, together with other Recommendations | International Standards, has been produced to facilitate the interconnection of information processing systems to provide directory services. A set of such systems, together with the directory information that they hold, can be viewed as an inte

34、grated whole, called the Directory. The information held by the Directory, collectively known as the Directory Information Base (DIB), is typically used to facilitate communication between, with or about objects such as application entities, people, terminals, and distribution lists. The Directory p

35、lays a significant role in Open Systems Interconnection, whose aim is to allow, with a minimum of technical agreement outside of the interconnection standards themselves, the interconnection of information processing systems: from different manufacturers; under different managements; of different le

36、vels of complexity; and of different ages. This Recommendation | International Standard defines a number of attribute types which may be found useful across a range of applications of the Directory, as well as a number of standard attribute syntaxes and matching rules. One particular use for many of

37、 the attributes defined herein is in the formation of names, particularly for the classes of objects defined in Rec. ITU-T X.521 | ISO/IEC 9594-7. This Recommendation | International Standard provides the foundation frameworks upon which industry profiles can be defined by other standards groups and

38、 industry forums. Many of the features defined as optional in these frameworks may be mandated for use in certain environments through profiles. This eighth edition technically revises and enhances the seventh edition of this Recommendation | International Standard. This eighth edition specifies ver

39、sions 1 and 2 of the Directory protocols. The first and second editions specified only version 1. Most of the services and protocols specified in this edition are designed to function under version 1. However some enhanced services and protocols, e.g., signed errors, will not function unless all Dir

40、ectory entities involved in the operation have negotiated version 2. Whichever version has been negotiated, differences between the services and between the protocols defined in the eight editions, except for those specifically assigned to version 2, are accommodated using the rules of extensibility

41、 defined in Rec. ITU-T X.519 | ISO/IEC 9594-5. Annex A, which is an integral part of this Recommendation | International Standard, provides the ASN.1 notation for the complete module which defines the attributes, attribute syntaxes and matching rules. Annex C, which is not an integral part of this R

42、ecommendation | International Standard, provides a table of attribute types, for easy reference. Annex D, which is not an integral part of this Recommendation | International Standard, provides an example of upper bounds value constraints. These constraints are not reflected in these Directory Speci

43、fications, but are provided as a reference for those implementations applying these constraints. Annex E, which is not an integral part of this Recommendation | International Standard, lists alphabetically the attributes and matching rules defined in this Directory Specification. Annex F, which is n

44、ot an integral part of this Recommendation | International Standard, gives examples relevant to the definition of zonal matching. Annex G, which is not an integral part of this Recommendation | International Standard, describes how a directory distinguished name may be based on object identifiers an

45、d on Uniform Resource Names (URNs). Annex H, which is not an integral part of this Recommendation | International Standard, describes an alternative way of generating directory distinguished based on object identifiers. It contains information retrieved from Rec. ITU-T X.660 | ISO/IEC 9834-1. Annex

46、I, which is not an integral part of this Recommendation | International Standard, lists the amendments and defect reports that have been incorporated to form this edition of this Recommendation | International Standard.

47、.520 (10/2016) 1 INTERNATIONAL STANDARD ITU-T RECOMMENDATION Information technology Open Systems Interconnection The Directory: Selected attribute types SECTION 1 GENERAL 1 Scope This Recommendation | International Standard defines a number of attribute types and matching rules which may be found us

48、eful across a range of applications of the Directory. Attribute types and matching rules fall into three categories, as described below. Some attribute types and matching rules are used by a wide variety of applications or are understood and/or used by the Directory itself. NOTE 1 It is recommended

49、that an attribute type or matching rule defined in this Recommendation | International Standard be used, in preference to the generation of a new one, whenever it is appropriate for the application. NOTE 2 The attribute and context types definitions by this Recommendation | International Standard have some associated semantics. Such specifications should not be used in situations where these semantics do not apply. Some attribute types and matching rules are intern
