10、EWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studyin

11、g technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups

12、which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO

13、and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions

14、(to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such word

15、s does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position conc

16、erning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by p

17、atents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

25、 and corrigenda. 100 ITU-T Rec. X.511 (11/2008) v Introduction This Recommendation | International Standard, together with the other Recommendations | International Standards, has been produced to facilitate the interconnection of information processing systems to provide directory services. A set o

26、f such systems, together with the directory information that they hold, can be viewed as an integrated 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

27、objects such as application entities, people, terminals, and distribution lists. The Directory plays 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 informatio

28、n processing systems: from different manufacturers; under different managements; of different levels of complexity; and of different ages. This Recommendation | International Standard defines the capabilities provided by the Directory to its users. This Recommendation | International Standard provid

29、es the foundation frameworks upon which industry profiles can be defined by other standards groups and industry forums. Many of the features defined as optional in these frameworks, may be mandated for use in certain environments through profiles. This sixth edition technically revises and enhances,

30、 but does not replace, the fifth edition of this Recommendation | International Standard. Implementations may still claim conformance to the fifth edition. However, at some point, the fifth edition will not be supported (i.e., reported defects will no longer be resolved). It is recommended that impl

31、ementations conform to this sixth edition as soon as possible. This sixth edition specifies versions 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. Howe

32、ver some enhanced services and protocols, e.g., signed errors, will not function unless all Directory 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 six editions, except fo

33、r those specifically assigned to version 2, are accommodated using the rules of extensibility defined in ITU-T Rec. X.519 | ISO/IEC 9594-5. Annex A, which is an integral part of this Recommendation | International Standard, provides the ASN.1 module for the Directory abstract service. Annex B, which

34、 is not an integral part of this Recommendation | International Standard, provides charts that describe the semantics associated with Basic Access Control as it applies to the processing of a Directory operation. Annex C, which is not an integral part of this Recommendation | International Standard,

35、 gives examples of the use of families of entries. Annex D, which is not an integral part of this Recommendation | International Standard, includes an updated copy of an external ASN.1 module referenced by this Directory Specification. Annex E, which is not an integral part of this Recommendation |

36、International Standard, lists the amendments and defect reports that have been incorporated to form this edition of this Recommendation | International Standard. ISO/IEC 9594-3:2008 (E) ITU-T Rec.
