ITU-T X.521 (10/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field o

14、f telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing

15、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 which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by

16、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 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate bot

17、h a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when

18、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 words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY

19、RIGHTSITU 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 concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by

20、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 patents, which may be required to implement this Recommendation. However, implementers are cautioned that thi

ITU-T X.521 (10/2016) v Introduction This Recommendation | International Standard, together with other Recommendations | International Standards, has been produced to facilitate the interconnection of information process

31、ing systems to provide directory services. A set of 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 t

32、o facilitate communication between, with or about 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 stand

33、ards themselves, the interconnection of information processing systems: from different manufacturers; under different managements; of different levels of complexity; and of different ages. This Recommendation | International Standard defines a number of attribute sets and object classes which may be

34、 found useful across a range of applications of the Directory. This Recommendation | International Standard provides 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 b

35、e mandated for use in certain environments through profiles. This eighth edition technically revises and enhances the seventh edition of this Recommendation | International Standard. This eight edition specifies versions 1 and 2 of the Directory protocols. The first and second editions specified onl

36、y 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 Directory entities involved in the operation have negotiated version 2. Whichever versio

37、n 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 defined in Rec. ITU-T X.519 | ISO/IEC 9594-5. Annex A, which is an integral part of

38、this Recommendation | International Standard, provides an ASN.1 module containing all of the type and value definitions which appear in this Recommendation | International Standard. Annex B, which is not an integral part of this Recommendation | International Standard, provides some common naming an

39、d structure rules which may or may not be used by administrative authorities. Annex C, 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 Standa

ITU-T X.521 (10/2016) 1 INTERNATIONAL STANDARD ITU-T RECOMMENDATION Information technology Open Systems Interconnection The Directory: Selected object classes SECTION 1 GENERAL 1 Scope This Recommendation | International Standard defines a number of object classes an

41、d name forms which may be found useful across a range of applications of the Directory. The definition of an object class involves listing a number of attribute types which are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and l

42、isting the attributes to be used in forming names for objects of that class. These definitions are used by the administrative authority which is responsible for the management of the directory information. Any administrative authority can define its own object classes or subclasses and name forms fo

43、r any purpose. NOTE 1 Those definitions may or may not use the notation specified in Rec. ITU-T X.501 | ISO/IEC 9594-2. NOTE 2 It is recommended that an object class defined in this Recommendation | International Standard, or a subclass derived from one, or a name form defined in this Recommendation

44、 | International Standard, be used in preference to the generation of a new one, whenever the semantics is appropriate for the application. Administrative authorities may support some or all the selected object classes and name forms, and may also add additional ones. All administrative authorities

45、shall support the object classes which the directory uses for its own purpose (the top, alias and Directory system agent (DSA) object classes). 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provis

46、ions of this Recommendation | International Standard. At the time of publication, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation | International Standard are encouraged to investigate the possibilit

47、y of applying the most recent editions of the Recommendations and Standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards.
