1. Background and Intended Use
In the late 1980s, X.500 Directory Services were standardised 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 directory pilots, RFC 1274 was published to
standardize 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] 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].
While much of the material in RFC 1274 has been superceed 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 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 COSINE schema elements.
1.1. Relationship to Other Documents
This document, together with [Schema] and [Syntaxes], obsoletes RFC
1274 in its entirety. [Schema] replaces Sections 9.3.1 (Userid) and
Section 9.3.21 (Domain Component) of RFC 1274. [Syntaxes] replaces
Zeilenga draft-zeilenga-ldap-cosine-01 [Page 3]
INTERNET-DRAFT COSINE Schema 23 October 2005
section 9.4 (Generally useful syntaxes) of RFC 1274.
This document replaces the remainder of RFC 1274. Appendix 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.
This document, together with [NamingPlan] and [Schema], obsoletes RFC
2247 in its entirety. [Schema] replaces Section 4 (Attribute Type
Definition) and Section 5.1 (The dcObject object class) of RFC 2247.
This document replaces Section 5.2 (The domain object class) of RFC
2247. The remainder of RFC 2247 is replaced by [NamingPlan].
Some of these items were described in RFC 2798 (inetOrgPerson schema).
This document supersedes these descriptions. This document, together
with [Schema], replaces 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].
Schema definitions are provided using LDAP description formats
[Models]. 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 domains [RFC1034] which
are associated with an object. For example, the entry in the DIT with
a DN <DC=example,DC=com> might have an associated domain of
"example.com".

'caseIgnoreIA5Match' and 'caseIgnoreIA5SubstringsMatch' rules are
described in [Syntaxes].
It is noted that the directory will not ensure that values of this
attribute conform to the <Mailbox> production [RFC2821]. It is the
application responsibility to ensure domains it stores in this
attribute are appropriately represented.
Additionally, the directory will compare values per the matching rules
named in the above attribute type description. As these rules differ
from rules which 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 by the
'caseIgnoreIA5Match' rule to be equal).
It is also noted that applications supporting internationalized domain
names SHALL use the ToASCII method [RFC3490] to produce <sub-domain>
components of the <Mailbox> production.

Note: X.520 also describes an attribute called 'uniqueIdentifier'
(2.5.4.45) which is called 'x500UniqueIdentifier' in LDAP
[Schema]. The attribute detailed here ought not be confused
with 'x500UniqueIdentifier'.
2.27. userClass
The 'userClass' attribute specifies categories of computer or
application user. The semantics placed on this attribute are for
local interpretation. Examples of current usage of this attribute in
academia are "student", "staff", "faculty", etc.. Note that the
'organizationalStatus' attribute type is now often be preferred as it
makes no distinction between persons as opposed to users.

4. Security Considerations
General LDAP security considerations [Roadmap] is applicable to the
use of this schema. Additional considerations are noted above where
appropriate.
Directories administrators should ensure that access to sensitive
information is restricted to authorized entities, but ensure 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 strong authentication and data security services
[AuthMeth].
5. IANA Considerations
It is requested that the Internet Assigned Numbers Authority (IANA)
update upon Standard Action the LDAP descriptors registry [BCP64bis]
as indicated the following template:

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.
Zeilenga draft-zeilenga-ldap-cosine-01 [Page 22]
INTERNET-DRAFT COSINE Schema 23 October 2005
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]) 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].
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]. For instance, the function
of the 'lastModifiedBy' and 'lastModifiedTime' attribute types is now
served by the 'creatorsName', 'createTimestamp', 'modifiersName', and
'modifyTimestamp' operational attributes [Models].
A.3. pilotPerson
The 'pilotPerson' object class was not brought forward as its function
is largely replaced by the 'organizationalPerson' [Models] object
class and its subclasses, such as 'inetOrgPerson' [RFC2798].
Most of the related attribute types (e.g., 'mail', 'manager', etc.)
were brought forward as they are used in other object classes.
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
Zeilenga draft-zeilenga-ldap-cosine-01 [Page 23]
INTERNET-DRAFT COSINE Schema 23 October 2005
related attribute types, were not brought forward as it as its use is
primarily experimental [QoS].
A.6. Attribute syntaxes
RFC 1274 defined and used caseIgnoreIA5StringSyntax attribute syntax.
This has been replaced with the IA5String syntax and approrpiate
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, 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.
