RFC 4524 COSINE LDAP/X.500 Schema June 2006

1. Introduction

In the late 1980s, X.500 Directory Services were standardised standardized by the
CCITT (Commite' Consultatif International de Telegraphique et
Telephonique), now a part of the ITU (International Telephone Union).
This lead to Directory Service piloting activities in the early
1990s, including the COSINE (Co-operation and Open Systems
Interconnection in Europe) PARADISE Project pilot [COSINEpilot] in
Europe. Motivated by needs large scale for large-scale directory pilots, RFC
1274 was published to standardize the directory schema and naming
architecture for use in the COSINE and other Internet X.500 pilots
[RFC1274].

In the years that followed, X.500 Directory Services have evolved to
incorporate new capabilities and even new protocols. In particular,
the Lightweight Directory Access Protocol (LDAP) [Roadmap] [RFC4510] was
introduced in the early 1990s [RFC1487], with Version 3 of LDAP
introduced in the late 1990s [RFC2251] and subsequently revised in the
2005 [Roadmap]. [RFC4510].

While much of the material in RFC 1274 has been superceed superceded by
subsequently published ITU-T Recommendations and IETF RFCs, many of
the schema elements lack standardized schema descriptions for use in
modern X.500 and LDAP directory services despite the fact that these
schema elements are in wide use today. As the old schema
descriptions cannot be used without adaptation, interoperabilty interoperability
issues may arise due to lack of standardized modern schema
descriptions.

This document addresses these issues by offering standardized schema
descriptions, where needed, for widely-used widely used COSINE schema elements.

1.1. Relationship to Other Documents

This document, together with [Schema] [RFC4519] and [Syntaxes], [RFC4517], obsoletes RFC
1274 in its entirety. [Schema] [RFC4519] replaces sections Sections 9.3.1 (Userid) and
9.3.21 (Domain Component) of RFC 1274. [Syntaxes] [RFC4517] replaces section

Zeilenga draft-zeilenga-ldap-cosine-02 [Page 3]

INTERNET-DRAFT COSINE Schema 6 February 2006 Section
9.4 (Generally useful syntaxes) of RFC 1274.

This document replaces the remainder of RFC 1274. Appendix A. A
discusses changes since RFC 1274, as well as why certain schema
elements were not brought forward in this revision of the COSINE
schema. All elements not brought are to be regarded as Historic.

The description of the 'domain' object class provided in this
document supercedes that found in RFC 2247. That is, section Section 3.4 of
this document replaces section Section 5.2 of [RFC2247].

Zeilenga Standards Track [Page 3]

RFC 2247. 4524 COSINE LDAP/X.500 Schema June 2006

Some of the schema elements specified here were described in RFC 2798
(inetOrgPerson schema). This document supersedes these descriptions.
This document, together with [Schema], [RFC4519], replaces section Section 9.1.3 of RFC
2798.

1.2. Terminology and 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 BCP 14 [RFC2119].

DIT stands for Directory Information Tree.
DN stands for Distinguished Name.
DSA stands for Directory System Agent, a server.
DSE stands for DSA-Specific Entry.
DUA stands for Directory User Agent, a client.

These terms are discussed in [Models]. [RFC4512].

Schema definitions are provided using LDAP description formats
[Models].
[RFC4512]. Definitions provided here are formatted (line wrapped)
for readability.

2. COSINE Attribute Types

This section details COSINE attribute types for use in LDAP.

2.1. associatedDomain

The 'associatedDomain' attribute specifies DNS [RFC1034][RFC2181]
host names [RFC1123] which that are associated with an object. That is,
values of this attribute should conform to the following ABNF:

domain = root / label *( DOT label )

Zeilenga draft-zeilenga-ldap-cosine-02 [Page 4]

INTERNET-DRAFT COSINE Schema 6 February 2006
root = SPACE
label = LETDIG [ *61( LETDIG / HYPHEN ) LETDIG ]
LETDIG = %x30-39 / %x41-5A / %x61-7A ; "0" - "9" / "A"-"Z" / "a"-"z"
SPACE = %x20 ; space (" ")
HYPHEN = %x2D ; hyphen ("-")
DOT = %x2E ; period (".")

For example, the entry in the DIT with a DN <DC=example,DC=com> might
have an associated domain of "example.com".

It is noted [RFC4517].

Note that the directory will not ensure that values of this attribute
conform to the <domain> production provided above. It is the application
application's responsibility to ensure that domains it stores in this
attribute are appropriately represented.

It is also noted

Also note that applications supporting Internationalized Domain Names
SHALL use the ToASCII method [RFC3490] to produce <label> components
of the <domain> production.

2.3. [RFC4517].

2.4. co

The 'co' (Friendly Country Name) attribute specifies names of
countries in human-readable format. For format, for example, "Germany" and
"Federal Republic of Germany". It is commonly used in conjunction
with the 'c' (Country Name) [Schema] [RFC4519] attribute (whose values are
restricted to the two-letter codes defined in [ISO3166]).

Additionally, the directory will compare values per the matching
rules named in the above attribute type description. As these rules
differ from rules which that normally apply to <Mailbox> comparisons,
operational issues may arise. For example, the assertion
(mail=joe@example.com) will match "JOE@example.com" even though the
<local-parts> differ. Also, where a user has two <Mailbox>es which whose
addresses differ only by case of the <local-part>, both cannot be
listed as values of the user's mail attribute (as they are considered
equal by the 'caseIgnoreIA5Match' rule to be equal).

4. Security Considerations

General LDAP security considerations [Roadmap] is [RFC4510] are applicable to the
use of this schema. Additional considerations are noted above where
appropriate.

Zeilenga Standards Track [Page 18]

RFC 4524 COSINE LDAP/X.500 Schema June 2006

Directories administrators should ensure that access to sensitive
information is be restricted to authorized entities, but ensure entities and that appropriate
data security services, including data integrity and data
confidentiality, are used to protect against eavesdropping.

Simple authentication (e.g., plain text passwords) mechanisms should
only be used when adequate data security services are in place. LDAP
offers reasonable reasonably strong authentication and data security services
[AuthMeth].
[RFC4513].

RFC 4524 COSINE LDAP/X.500 Schema June 2006

Appendix A. Changes since RFC 1274

This document represents a substantial rewrite of RFC 1274. The
following sections summarize the substantive changes.

A.1. LDAP Short Names

A number of COSINE attribute types have short names in LDAP.

X.500 Name LDAP Short Name
------------- ---------------
domainComponent dc
favoriteDrink drink
friendCountryName co
homeTelephoneNumber homePhone
mobileTelephoneNumber mobile
pagerTelephoneNumber pager
rfc822Mailbox mail
userid uid

While the LDAP short names are generally used in LDAP, some
implementations may (for legacy reasons [Historic]) [RFC3494]) recognize the
attribute type by its X.500 name. Hence, the X.500 names have been
reserved solely for this purpose.

Note: 'uid' and 'dc' are described in [Schema]. [RFC4519].

A.2. pilotObject

The 'pilotObject' object class was not brought forward as its
function is largely replaced by operational attributes introduced in
X.500(93) [X.501] and version 3 of LDAP [Models]. [RFC4512]. For instance, the
function of the 'lastModifiedBy' and 'lastModifiedTime' attribute
types is now served by the 'creatorsName', 'createTimestamp',
'modifiersName', and 'modifyTimestamp' operational attributes [Models].
[RFC4512].

A.3. pilotPerson

The 'pilotPerson' object class was not brought forward as its
function

Zeilenga draft-zeilenga-ldap-cosine-02 [Page 23]

INTERNET-DRAFT COSINE Schema 6 February 2006 is largely replaced by the 'organizationalPerson' [Models] [RFC4512]
object class and its subclasses, such as 'inetOrgPerson' [RFC2798].

Most of the related attribute types (e.g., 'mail', 'manager', etc.) 'manager') were
brought forward as they are used in other object classes.

RFC 4524 COSINE LDAP/X.500 Schema June 2006

A.4. dNSDomain

The 'dNSDomain' object class and related attribute types were not
brought forward as its use is primarily experimental [RFC1279].

A.5. pilotDSA and qualityLabelledData

The 'pilotDSA' and 'qualityLabelledData' object classes, as well as
related attribute types, were not brought forward as it as its use is
primarily experimental [QoS].

A.6. Attribute syntaxes Syntaxes

RFC 1274 defined and used caseIgnoreIA5StringSyntax attribute syntax.
This has been replaced with the IA5String syntax and approrpiate appropriate
matching rules in 'mail' and 'associatedDomain'.

RFC 1274 restricted 'mail' to have non-zero length values. This
restriction is not reflected in the IA5String syntax used in the
definitions provided in this specification. However, as values are
to conform to the <Mailbox> production, the 'mail' should not contain
zero-length values. Unfornuately, Unfortunately, the directory service will not
enforce this restriction.

Appendix B. Changes since RFC 2247

The 'domainNameForm' name form was not brought forward as
specification of name forms used in LDAP is left to a future
specification.
