33、0/2016) 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 of such systems, together with the direct
34、ory 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 objects such as application entities, pe
35、ople, 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 information processing systems: from different man
36、ufacturers; 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 provides the foundation frameworks upon which
37、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 eighth edition technically revises and enhances the seventh edition of this Recommendati
38、on | International Standard. This eighth 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. However, some enhanced services and p
39、rotocols, 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 eight editions, except for those specifically assigned
40、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 this Recommendation | International Standard, provides the ASN.1 module for the Directory abstract service. Annex B, which is not an integral part of th
41、is 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, gives examples of the use of
42、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 | International Standard, provid
43、es a suggested technique for Bind protected password. Annex F, 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.

45、xternally visible service provided by the Directory. This Recommendation | International Standard does not specify individual implementations or products. 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, consti
46、tute provisions 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
47、 possibility of applying the most recent edition of the Recommendations and Standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards. The Telecommunication Standardization Bureau of the ITU maintains a list of currently valid ITU-T Recommendations.
