RFC 4524 COSINE LDAP/X.500 Schema June 2006 1. Introduction In the late 1980s, X.500 Directory Services were 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 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) [RFC4510] was introduced in the early 1990s [RFC1487], with Version 3 of LDAP introduced in the late 1990s [RFC2251] and subsequently revised in 2005 [RFC4510]. While much of the material in RFC 1274 has been superceded by subsequently published ITU-T Recommendations and IETF RFCs, many of the schema elements lack standardized schema descriptions for use in modern X.500 and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, 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 COSINE schema elements. 1.1. Relationship to Other Documents This document, together with [RFC4519] and [RFC4517], obsoletes RFC 1274 in its entirety. [RFC4519] replaces Sections 9.3.1 (Userid) and 9.3.21 (Domain Component) of RFC 1274. [RFC4517] replaces 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. The description of the 'domain' object class provided in this document supercedes that found in RFC 2247. That is, Section 3.4 of this document replaces Section 5.2 of [RFC2247]. Zeilenga Standards Track [Page 3]
RFC 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 [RFC4519], 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 [RFC4512]. Schema definitions are provided using LDAP description formats [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] that are associated with an object. That is, values of this attribute should conform to the following ABNF: domain = root / label *( DOT label ) 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".

Note that the directory will not ensure that values of this attribute conform to the <domain> production provided above. It is the application's responsibility to ensure that domains it stores in this attribute are appropriately represented. Also note that applications supporting Internationalized Domain Names SHALL use the ToASCII method [RFC3490] to produce <label> components of the <domain> production. 2.2. associatedName The 'associatedName' attribute specifies names of entries in the organizational DIT associated with a DNS domain [RFC1034][RFC2181].

RFC 4524 COSINE LDAP/X.500 Schema June 2006 Note that the directory will not ensure that values of this attribute conform to the <Mailbox> production [RFC2821]. It is the application's responsibility to ensure that 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 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 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). Also note that applications supporting internationalized domain names SHALL use the ToASCII method [RFC3490] to produce <sub-domain> components of the <Mailbox> production. 2.17. manager The 'manager' attribute specifies managers, by distinguished name, of the person (or entity).

RFC 4524 COSINE LDAP/X.500 Schema June 2006 Directories administrators should ensure that access to sensitive information be restricted to authorized 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 reasonably strong authentication and data security services [RFC4513]. 5.

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 [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 [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 [RFC4512]. For instance, the function of the 'lastModifiedBy' and 'lastModifiedTime' attribute types is now served by the 'creatorsName', 'createTimestamp', 'modifiersName', and 'modifyTimestamp' operational attributes [RFC4512]. A.3. pilotPerson The 'pilotPerson' object class was not brought forward as its function is largely replaced by the 'organizationalPerson' [RFC4512] object class and its subclasses, such as 'inetOrgPerson' [RFC2798]. Most of the related attribute types (e.g., 'mail', 'manager') were brought forward as they are used in other object classes. Zeilenga Standards Track [Page 23]
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 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 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. 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. Editor's Address Kurt D.
