18、94-5:2001(E) ISO/IEC 2001 All rights reserved vForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the develo
19、pment of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-government
20、al, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the
21、 joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. At
22、tention is drawn to the possibility that some of the elements of this part of ISO/IEC 9594 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Users and implementors should note the existence of a “defect resolution” procedure
23、 in ISO/IEC JTC 1 to identify and correct errors in International Standards through the publication of Technical Corrigenda. Identical corrections are made to the corresponding ITU-T Recommendations through Corrigenda and may also be made in the form of Implementors Guides. Details of Technical Corr
24、igenda to International Standards are available on the ISO website; published Technical Corrigenda can be obtained via the ISO webstore or from the ISO and IEC national bodies. Corrigenda and Implementors Guides to ITU-T Recommendations can be obtained from the ITU-T website. ISO/IEC 9594-5 was prep
25、ared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems, in collaboration with ITU-T. The identical text is published as ITU-T Rec. X.519. This fourth edition of ISO/IEC 9594-5 constitutes a technical rev
26、ision of the third edition (ISO/IEC 9594-5:1998), which is provisionally retained in order to support implementations based on the third edition. This edition also incorporates Corrigendum 1:2002.

Annex I is for information only. ISO/IEC 9594-5:2001(E) vi ISO/IEC 2001 All rights reserved Introduction This
29、 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 directory information that they h
30、old, 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, people, terminals and distrib
31、ution 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 manufacturers; under different
32、managements; of different levels of complexity; and of different ages. This Recommendation | International Standard specifies the application service elements and application contexts for two protocols the Directory Access Protocol (DAP) and the Directory System Protocol (DSP). The DAP provides for
33、access to the Directory to retrieve or modify Directory information. The DSP provides for the chaining of requests to retrieve or modify Directory information to other parts of the distributed Directory System where the information may be held. In addition this Recommendation | International Standar
34、d specifies the application service elements and application contexts for the Directory Information Shadowing Protocol (DISP) and the Directory Operational Binding Management Protocol (DOP). The DISP provides for the shadowing of information held in one DSA to another DSA. The DOP provides for the e
35、stablishment, modification and termination of bindings between pairs of DSAs for the administration of relationships between the DSAs (such as for shadowing or hierarchical relationships). This fourth edition technically revises and enhances, but does not replace, the third edition of this Recommend
36、ation | International Standard. Implementations may still claim conformance to the third edition. However, at some point, the third edition will not be supported (i.e. reported defects will no longer be resolved). It is recommended that implementations conform to this fourth edition as soon as possi
37、ble. This fourth edition specifies version 1 and version 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. sig
38、ned 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 four editions, except for those specifically assigned to version 2, are ac
39、commodated using the rules of extensibility defined in this edition of ITU-T Rec. X.519 | ISO/IEC 9594-5. This Directory Specification also specifies an alternative version of the DAP, DSP, DISP and DOP protocols, known as DAP-IP, DSP-IP, DISP-IP and DOP-IP respectively, which are mappings of the co
40、rresponding abstract services directly onto the TCP/IP protocol instead of onto an OSI stack. These alternative protocols allow support of Directory service elements without the implementation overhead of supporting a full OSI stack. Annex A, which is an integral part of this Recommendation | Intern
41、ational Standard, provides the ASN.1 module for the directory access protocol. Annex B, which is an integral part of this Recommendation | International Standard, provides the ASN.1 module for the directory system protocol. Annex C, which is an integral part of this Recommendation | International St
42、andard, provides the ASN.1 module for the directory information shadowing protocol. Annex D, which is an integral part of this Recommendation | International Standard, provides the ASN.1 module for the directory operational binding management protocol. Annex E, which is an integral part of this Reco
43、mmendation | International Standard, provides the ASN.1 module for the IDM protocol specification. ISO/IEC 9594-5:2001(E) ISO/IEC 2001 All rights reserved viiAnnex F, which is an integral part of this Recommendation | International Standard, provides the ASN.1 module for the Directory IDM protocols.
44、 Annex G, which is an integral part of this Recommendation | International Standard, provides the ASN.1 module which contains all the ASN.1 object identifiers assigned in this Recommendation | International Standard. Annex H, which is an integral part of this Recommendation | International Standard,
45、 provides the ASN.1 module which contains all the ASN.1 object identifiers assigned to identify operational binding types in this series of Recommendations | International Standards. Annex I, which is not an integral part of this Recommendation | International Standard, lists the amendments and defe
46、ct reports that have been incorporated to form this edition of this Recommendation | International Standard.
