Abstract
This document provides an overview of attribute types and object
classes defined by the ISO/IEC JTC1 and ITU-T committees in the
IS0/IEC 9594 and X.500 documents, in particular those intended for
use by directory clients. This is the most widely used schema for
LDAP/X.500 directories. It is used as a basis for many other white
pages objects schema definitions. This document does not cover
attributes used for the administration of X.500 directory servers,
nor does it include attributes defined by other ISO/ITU-T documents.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].

1. General Issues
This document references Syntaxes given in Section 3 of [Syntaxes]
and Matching Rules specified in Section 4 of [Syntaxes].
The definitions of Attribute Types and Object Classes are written
using the ABNF form of AttributeTypeDescription and
ObjectClassDescription given in [Models]. Lines have been folded
for readability.
2. Source
The schema definitions in this document are based on those found in
the X.500-series [X.520] and [X.521] and RFC 2247 [RFC2247],
specifically:
Sections Source
============ ==================
3.1 - 3.3 X.520 [X.520]
3.4 RFC 2247 [RFC2247]
3.5 - 3.42 X.520 [X.520]
4.1 - 4.3 X.521 [X.521]
4.4 RFC 2247 [RFC2247]
4.5 - 4.13 X.521 [X.521]
3. Attribute Types
The Attribute Types contained in this section hold user information.
There is no requirement that servers implement the following
Attribute Types:
searchGuide
teletexTerminalIdentifier
In fact, their use is greatly discouraged.
An LDAP server implementation SHOULD recognize the rest of the
Attribute Types described in this section.
3.1 businessCategory
This Attribute Type describes the kind of business performed by
an organization.

( 2.5.4.15 NAME 'businessCategory'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{128} )
The SYNTAX oid indicates the Directory String syntax.
3.2 c
This is the X.520 [X.520] countryName Attribute Type, which contains
a two-letter ISO 3166 [ISO3166]country code.
( 2.5.4.6 NAME 'c'
SUP name
SINGLE-VALUE )
3.3 cn
This is the X.520 [X.520] commonName Attribute Type, which contains
a name of an object. If the object corresponds to a person, it is
typically the person's full name.
( 2.5.4.3 NAME 'cn'
SUP name )
3.4 dc
The dc (short for domainComponent) attribute type is defined as
follows:
( 0.9.2342.19200300.100.1.25 NAME 'dc'
EQUALITY caseIgnoreIA5Match
SUBSTR caseIgnoreIA5SubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.26
SINGLE-VALUE )
The value of this attribute is a string holding one component of a
DNS domain name. The encoding of IA5String for use in LDAP is simply
the characters of the string itself. The equality matching rule is
case insensitive, as is today's DNS.
3.5 description
This Attribute Type contains a human-readable description of
the object.
( 2.5.4.13 NAME 'description'

3.7 distinguishedName
This Attribute Type is not used as the name of the object itself,
but it is instead a base type from which attributes with DN syntax
inherit.

entry. LDAP server implementations which do not support attribute
subtyping need not recognize this attribute in requests. Client
implementations MUST NOT assume that LDAP servers are capable of
performing attribute subtyping.
( 2.5.4.49 NAME 'distinguishedName'
EQUALITY distinguishedNameMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )

3.8 dnQualifier
The dnQualifier Attribute Type specifies disambiguating information
to add to the relative distinguished name of an entry. It is
intended for use when merging data from multiple sources in order to
prevent conflicts between entries which would otherwise have the same
name. It is recommended that the value of the dnQualifier attribute
be the same for all entries from a particular source.

3.11 generationQualifier
The generationQualifier Attribute Type contains the part of a
person's name which typically is the suffix, as in "IIIrd".
( 2.5.4.44 NAME 'generationQualifier'

A value of this Attribute Type is the Distinguished Name of an
object that is on a list or in a group.
( 2.5.4.31 NAME 'member'
SUP distinguishedName )
3.18 name
The name Attribute Type is the attribute supertype from which string
Attribute Types typically used for naming may be formed. It is
unlikely that values of this type itself will occur in an entry.
LDAP server implementations which do not support attribute subtyping
need not recognize this attribute in requests. Client
implementations MUST NOT assume that LDAP servers are capable of
performing attribute subtyping.

5. Security Considerations
Attributes of directory entries are used to provide descriptive
information about the real-world objects they represent, which can be
people, organizations or devices. Most countries have privacy laws
regarding the publication of information about people.
Transfer of cleartext passwords is strongly discouraged where the
underlying transport service cannot guarantee confidentiality and may
result in disclosure of the password to unauthorized parties.
It is required that strong authentication be performed in order to
modify directory entries using LDAP.
Several X.500 Attribute Types and Object Classes, such as, the
userCertificate Attribute Type or the certificationAuthority Object
Class, are used to include key-based security information in
directory entries. The Attribute Types are:
authorityRevocationList
cACertificate
certificateRevocationList
crossCertificatePair
deltaRevocationList
supportedAlgorithms
userCertificate
The Object Classes are:
certificationAuthority
certificationAuthority-V2
cRLDistributionPoint
strongAuthenticationUser
userSecurityInformation
These Attribute Types and Object Classes are specified for LDAP by
the PKIX Working Group, and so, are not included in this document.
It is recommended that the BNF notation in RFC 1778 [RFC1778] not
be used for User Certificate, Authority Revocation List, and
Certificate Pair.
6. Acknowledgements
The definitions, on which this document is based, have been developed
by committees for telecommunications and international standards.
No new attribute definitions have been added.

Annex A Change Log
This annex lists the changes that have been made from RFC 2256 to
this I-D.
Changes to RFC 2256 resulting in
draft-ietf-ldapbis-user-schema-00.txt:
1. Revision of the Status of this Memo.
2. Dependencies on RFC 1274 have been eliminated.
3. The references to X.500(96) have been expressed in terms of
the "edition", rather than the standard date. Note that the
version of X.500 which is the basis for this document, is the
third edition, which was finalized in 1996, but approved in
1997.
4. The "teletexTerminalNumber" attribute and syntax are marked
as obsolete.
5. Removed "The syntax definitions are based on the ISODE "QUIPU"
implementation of X.500." from section 6.
6. Added text to 6.1, the octetString syntax, in accordance
with X.520.
7. Some of the attribute types MUST be recognized by servers.
Also, several attributes are obsolete. Therefore, the
various kinds of attribute types have been placed in separate
sections:
- necessary for the directory to operate (section 3.1)
- for holding user information (section 3.2)
- superseded or withdrawn (section 3.3).
8. Since "top" may be implicitly specified and "alias" is not
abstract, the last sentence in the description of the
"objectClass" attribute type, section 3.1.1, has been deleted.
The clause that preceded the deleted sentence has been
removed, also.
9. Add a description to the definition of the "telephoneNumber"
attribute type, section 3.2.17.
10. Add text to mark the "teletexTerminalIdentifier" attribute
type as obsolete.

INTERNET-DRAFT draft-ietf-ldapbis-user-schema-04 25 February 2003
11. Add a security consideration requiring strong authentication
in order to modify directory entries.
Changes to draft-ietf-ldapbis-user-schema-00.txt, resulting in draft-
ietf-ldapbis-user-schema-01.txt:
12. Delete the conformance requirement for subschema object
classes in favor of a statement in [SYNTAX].
13. Add a Table of Contents
14. Replace the term "obsolete" with "superseded or withdrawn"
15. Added explanations to many attributes.
16. In the title, correct the X.500 reference to have the second
edition as the basis.
17. Throughout this I-D, cleaned up whitespace in the BNF
definitions.
18. Removed Section 4, Syntaxes, and Section 6, Matching Rules,
(moved to draft-ietf-ldapbis-syntaxes-01.txt).
19. Reorganized Section 3, Attributes, to eliminate grouping
attributes according to conformance requirements. Reordered
Section 3, Attributes, and Section 4, Object Classes,
alphabetically.
20. Added an explanation for each object class.
Changes to draft-ietf-ldapbis-user-schema-01.txt, resulting in draft-
ietf-ldapbis-user-schema-02.txt:
21. Removed the certificate-related Attribute Types:
authorityRevocationList,
cACertificate,
certificateRevocationList,
crossCertificatePair,
deltaRevocationList,
supportedAlgorithms, and
userCertificate.
Removed the certificate-related Object Classes:
certificationAuthority,
certificationAuthority-V2,
cRLDistributionPoint,
strongAuthenticationUser, and
userSecurityInformation

INTERNET-DRAFT draft-ietf-ldapbis-user-schema-04 25 February 2003
Noted in the Security Considerations (Section 7) that they
are covered in PKIX WG documents.
22. Removed the dmdName Attribute Type and dmd Object Class
because they are not in the version of X.500 which
is referenced.
23. Removed embedded comments from the ABNF productions
throughout the document.
24. Cleaned up the references; adopted word instead of number
tags; split Section 7 into normative and informative
subsections.
Changes to draft-ietf-ldapbis-user-schema-02.txt, resulting in draft-
ietf-ldapbis-user-schema-03.txt:
......25. Deleted the 'aliasedObjectName' and 'objectClass' attribute
type definitions. They are included in [Models].
26. Deleted the 'alias' and 'top' object class definitions. They
are included in [Models].
27. Replaced the document title.
28. Changed reference citations to be consistent with the rest of
the LDAPbis documents.
Changes to draft-ietf-ldapbis-user-schema-03.txt, resulting in draft-
ietf-ldapbis-user-schema-04.txt:
29. Added references for RFC 2026 and RFC 2247.
30. Corrected the copyright year.
31. Added the 'dc' attribute and the 'domain' object class from
RFC 2247.
