             Lightweight Directory Access Protocol (LDAP):
                    Technical Specification Road Map

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

   The Lightweight Directory Access Protocol (LDAP) is an Internet
   protocol for accessing distributed directory services that act in
   accordance with X.500 data and service models.  This document
   provides a road map of the LDAP Technical Specification.

1.  The LDAP Technical Specification

   The technical specification detailing version 3 of the Lightweight
   Directory Access Protocol (LDAP), an Internet Protocol, consists of
   this document and the following documents:

      LDAP: The Protocol [RFC4511]
      LDAP: Directory Information Models [RFC4512]
      LDAP: Authentication Methods and Security Mechanisms [RFC4513]
      LDAP: String Representation of Distinguished Names [RFC4514]
      LDAP: String Representation of Search Filters [RFC4515]
      LDAP: Uniform Resource Locator [RFC4516]
      LDAP: Syntaxes and Matching Rules [RFC4517]
      LDAP: Internationalized String Preparation [RFC4518]
      LDAP: Schema for User Applications [RFC4519]

RFC 4510                   LDAP: TS Road Map                   June 2006

   The terms "LDAP" and "LDAPv3" are commonly used to refer informally
   to the protocol specified by this technical specification.  The LDAP
   suite, as defined here, should be formally identified in other
   documents by a normative reference to this document.

   LDAP is an extensible protocol.  Extensions to LDAP may be specified
   in other documents.  Nomenclature denoting such combinations of
   LDAP-plus-extensions is not defined by this document but may be
   defined in some future document(s).  Extensions are expected to be
   truly optional.  Considerations for the LDAP extensions described in
   BCP 118, RFC 4521 [RFC4521] fully apply to this revision of the LDAP
   Technical Specification.

   IANA (Internet Assigned Numbers Authority) considerations for LDAP
   described in BCP 64, RFC 4520 [RFC4520] apply fully to this revision
   of the LDAP technical specification.

1.1.  Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   document are to be interpreted as described in BCP 14 [RFC2119].

2.  Relationship to X.500

   This technical specification defines LDAP in terms of [X.500] as an
   X.500 access mechanism.  An LDAP server MUST act in accordance with
   the X.500 (1993) series of International Telecommunication Union -
   Telecommunication Standardization (ITU-T) Recommendations when
   providing the service.  However, it is not required that an LDAP
   server make use of any X.500 protocols in providing this service.
   For example, LDAP can be mapped onto any other directory system so
   long as the X.500 data and service models [X.501][X.511], as used in
   LDAP, are not violated in the LDAP interface.

   This technical specification explicitly incorporates portions of
   X.500(93).  Later revisions of X.500 do not automatically apply to
   this technical specification.

3.  Relationship to Obsolete Specifications

   This technical specification, as defined in Section 1, obsoletes
   entirely the previously defined LDAP technical specification defined
   in RFC 3377 (and consisting of RFCs 2251-2256, 2829, 2830, 3771, and
   3377 itself).  The technical specification was significantly

   This document replaces RFC 3377 as well as Section 3.3 of RFC 2251.
   [RFC4512] replaces portions of RFC 2251, RFC 2252, and RFC 2256.
   [RFC4511] replaces the majority RFC 2251, portions of RFC 2252, and
