Information technology — Open Systems Interconnection — The Directory: Selected object classes — Part 7:
ISO/IEC 9594-7:2008 defines a number of object classes and name forms that 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 that are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and listing the attributes to be used in forming names for objects of that class. These definitions are used by the administrative authority that is responsible for the management of the directory information. Any administrative authority can define its own object classes or subclasses and name forms for any purpose. Such definitions can optionally use the notation specified in ISO/IEC 9594-2. It is recommended that an object class defined in ISO/IEC 9594-7:2008, or a subclass derived from one, or a name form defined in ISO/IEC 9594-7:2008, 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 of the selected object classes and name forms, and may also add additional ones. All administrative authorities shall support the object classes that the directory uses for its own purposes (the top, alias and DSA object classes).

Foreword
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 development 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-governmental, 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 2.
The main task of the 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 9594-7:2008 was prepared 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.521 (11/2008).
This sixth edition cancels and replaces the fifth edition (ISO/IEC 9594-7:2005), which has been technically
revised.
ISO/IEC 9594 consists of the following parts, under the general title Information technology — Open Systems

ISO/IEC 9594-7:2008(E)
Introduction
This Recommendation | International 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 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 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 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 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 be mandated for use in certain environments through profiles. This sixth edition technically revises and enhances,
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 implementations 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. 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 version has been
negotiated, differences between the services and between the protocols defined in the six editions, except for 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 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 and 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 Standard.

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 and 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 listing 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 for any purpose.
NOTE 1 – Those definitions may or may not use the notation specified in ITU-T Rec. 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 | 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 shall support the object classes which the directory uses for its own purpose (the top, alias
and DSA object classes).
2 Normative references
The following Recommendations and International Standards contain provisions which, through reference in this text,
