INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
Abstract
This document is an integral part of the Lightweight Directory Access
Protocol (LDAP) technical specification [Roadmap]. It provides a
technical specification of attribute types and object classes
intended for use by LDAP directory clients for many directory
services, such as, White Pages. These objects are widely used as a
basis for the schema in many LDAP directories. This document does
not cover attributes used for the administration of directory
servers, nor does it include directory objects defined for specific
uses in other documents.

INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
1. Introduction
This document provides an overview of attribute types and object
classes intended for use by Lightweight Directory Access Protocol
(LDAP) directory clients for many directory services, such as, White
Pages. Originally specified in the X.500 [X.500] documents, these
objects are widely used as a basis for the schema in many LDAP
directories. This document does not cover attributes used for the
administration of directory servers, nor does it include directory
objects defined for specific uses in other documents.
1.1 Relationship with other specifications
This document is an integral part of the LDAP technical specification
[Roadmap] which obsoletes the previously defined LDAP technical
specification, RFC 3377, in its entirety. In terms of RFC 2256,
Sections 6 and 8 of RFC 2256 are obsoleted by [Syntaxes]. Sections
5.1, 5.2, 7.1 and 7.2 of RFC 2256 are obsoleted by [Models]. The
remainder of RFC 2256 is obsoleted by this document. Section 2.4 of
this document supersedes the technical specification for the 'dc'
attribute type and 'dcObject' object class found in RFC 2247. The
remainder of RFC 2247 remains in force.
This document updates RFC 2798 by replacing the informative
description of the 'uid' attribute type, with the definitive
description provided in Section 2.39 of this document.
A number of schema elements which were included in the previous
revision of the LDAP Technical Specification are not included in this
revision of LDAP. PKI-related schema elements are now specified in
[LDAP-PKI]. Unless reintroduced in future technical specifications,
the remainder are to be considered Historic.
The descriptions in this document SHALL be considered definitive for
use in LDAP.
1.2 Conventions
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].
1.3 General Issues
This document references Syntaxes defined in Section 3 of [Syntaxes]
and Matching Rules defined in Section 4 of [Syntaxes].
The definitions of Attribute Types and Object Classes are written
Sciberras Expires 30 July 2006 [Page 5]
INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
using the Augmented Backus-Naur Form (ABNF) [RFC4234] of
AttributeTypeDescription and ObjectClassDescription given in
[Models]. Lines have been folded for readability. When such values
are transferred as attribute values in the LDAP Protocol the values
will not contain line breaks.
2. Attribute Types
The Attribute Types contained in this section hold user information.
There is no requirement that servers implement the 'searchGuide' and
'teletexTerminalIdentifier' attribute types. In fact, their use is
greatly discouraged.
An LDAP server implementation SHOULD recognize the rest of the
attribute types described in this section.
2.1 'businessCategory'
The 'businessCategory' attribute type describes the kinds of business
performed by an organization. Each kind is one value of this
multi-valued attribute.

1.3.6.1.4.1.1466.115.121.1.15 refers to the Directory String syntax
[Syntaxes].
Examples: "banking", "transportation" and "real estate".
2.2 'c'
The 'c' ('countryName' in X.500) attribute type contains a two-letter
ISO 3166 [ISO3166] country code.

[Syntaxes].

INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
Examples: "DE", "AU" and "FR".
2.3 'cn'
The 'cn' ('commonName' in X.500) attribute type contains names of an
object. Each name is one value of this multi-valued attribute. If
the object corresponds to a person, it is typically the person's full
name.
(Source: X.520 [X.520])
( 2.5.4.3 NAME 'cn'
SUP name )
Examples: "Martin K Smith", "Marty Smith" and "printer12".
2.4 'dc'
The 'dc' ('domainComponent' in RFC 2247) attribute type is a string
holding one component, a label, of a DNS domain name [RFC1034]. The
encoding of IA5String for use in LDAP is simply the characters of the
ASCII label. The equality matching rule is case insensitive, as is
today's DNS.
(Source: RFC 2247 [RFC2247])
( 0.9.2342.19200300.100.1.25 NAME 'dc'
EQUALITY caseIgnoreIA5Match
SUBSTR caseIgnoreIA5SubstringsMatch

SINGLE-VALUE )
1.3.6.1.4.1.1466.115.121.1.26 refers to the IA5 String syntax
[Syntaxes].
Examples: Valid values include "example" and "com". The value
"example.com" is invalid, because it contains two label
components.
Directory applications supporting International Domain Names SHALL
use the ToASCII method [RFC3490] to produce the domain name component
label. The special considerations discussed in section 4 of RFC 3490
[RFC3490] should be taken, depending on whether the domain component
is used for "stored" or "query" purposes.

2.5 'description'
The 'description' attribute type contains human-readable descriptive
phrases about the object. Each description is one value of this
multi-valued attribute.

[Syntaxes].
Examples: "a color printer", "Maintenance is done every Monday, at
1pm." and "distribution list for all technical staff".
2.6 'destinationIndicator'
The 'destinationIndicator' attribute type contains country and city
strings, associated with the object (the addressee), needed to
provide the Public Telegram Service. The strings are composed in
accordance with CCITT Recommendations F.1 [F.1] and F.31 [F.31].
Each string is one value of this multi-valued attribute.

1.3.6.1.4.1.1466.115.121.1.44 refers to the Printable String syntax
[Syntaxes].
Examples: "AASD" as a destination indicator for Sydney, Australia.
"GBLD" as a destination indicator for London, United
Kingdom.
It is noted that the directory will not ensure that values of this
attribute conform to the F.1 and F.30 CCITT Recommendations. It is
the application's responsibility to ensure destination indicators
that it stores in this attribute are appropriately constructed.
2.7 'distinguishedName'
The 'distinguishedName' attribute type is not used as the name of the
object itself, but it is instead a base type from which some user
Sciberras Expires 30 July 2006 [Page 8]
INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
attribute types with a DN syntax can inherit.
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.

1.3.6.1.4.1.1466.115.121.1.12 refers to the DN syntax [Syntaxes].
2.8 'dnQualifier'
The 'dnQualifier' attribute type contains disambiguating information
strings to add to the relative distinguished name of an entry. The
information is intended for use when merging data from multiple
sources in order to prevent conflicts between entries which would
otherwise have the same name. Each string is one value of this
multi-valued attribute. It is recommended that a value of the
'dnQualifier' attribute be the same for all entries from a particular
source.

[Syntaxes].
Examples: "20050322123345Z" - timestamps can be used to disambiguate
information.
"123456A" - serial numbers can be used to disambiguate
information.
2.9 'enhancedSearchGuide'
The 'enhancedSearchGuide' attribute type contains sets of information
for use by directory clients in constructing search filters. Each
set is one value of this multi-valued attribute.

Examples: "cn=James Clarke,ou=Finance,o=Widget\, Inc." and
"cn=John Xerri,ou=Finance,o=Widget\, Inc." may
be two members of the financial team (group) at Widget,
Inc. In which case, both of these distinguished names would
be present as individual values of the member attribute.
2.18 'name'
The 'name' attribute type is the attribute supertype from which user
attribute types with the name syntax inherit. Such attribute types
are typically used for naming. The attribute type is multi-valued.
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.

1.3.6.1.4.1.1466.115.121.1.40 refers to the Octet String syntax
[Syntaxes].
Passwords are stored using an Octet String syntax and are not
encrypted. 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.
An example of a need for multiple values in the 'userPassword'
attribute is an environment where every month the user was expected
to use a different password generated by some automated system.
During transitional periods, like the last and first day of the
periods, it may be necessary to allow two passwords for the two
consecutive periods to be valid in the system.

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

INTERNET-DRAFT LDAP: Schema for User Applications January 30, 2006
regarding the publication of information about people.
Transfer of cleartext passwords is strongly discouraged where the
underlying transport service cannot guarantee confidentiality and
integrity, since this may result in disclosure of the password to
unauthorized parties.
Multiple attribute values for the 'userPassword' attribute need to be
used with care. Especially reset/deletion of a password by an admin
without knowing the old user password gets tricky or impossible if
multiple values for different applications are present.
Certainly, applications which intend to replace the 'userPassword'
value(s) with new value(s) should use modify/replaceValues (or
modify/deleteAttribute+addAttribute). Additionally, server
implementations are encouraged to provide administrative controls
which, if enabled, restrict the 'userPassword' attribute to one
value.
Note that when used for authentication purposes [AuthMeth], the user
need only prove knowledge of one of the values, not all of the
values.

by committees for telecommunications and international standards.
This document is an update of RFC 2256 by Mark Wahl. RFC 2256 was a
product of the IETF ASID Working Group.
The 'dc' attribute type definition and the 'dcObject' object class
definition in this document supersede the specification in RFC 2247
by S. Kille, M. Wahl, A. Grimstad, R. Huber, and S. Sataluri.
The 'uid' attribute type definition in this document supersedes the
specification of the 'userid' in RFC 1274 by P. Barker and S. Kille
and of the uid in RFC 2798 by M. Smith.
The 'uidObject' object class definition in this document supersedes
the specification of the 'uidObject' in RFC 2377 by A. Grimstad, R.
Huber, S. Sataluri and M. Smith.
This document is based upon input of the IETF LDAPBIS working group.
