INTERNET-DRAFT        draft-ietf-ldapbis-roadmap-08    30 September 2005


Abstract

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


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].


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 [Protocol],
      LDAP: Directory Information Models [Models],
      LDAP: Authentication Methods and Connection Level Security
            Mechanisms [AuthMeth],
      LDAP: String Representation of Distinguished Names [LDAPDN],
      LDAP: String Representation of Search Filters [Filters],
      LDAP: Uniform Resource Locator [LDAPURL],
      LDAP: Syntaxes and Matching Rules [Syntaxes],
      LDAP: Internationalized String Preparation [LDAPprep], and
      LDAP: User Schema [Schema].

  The terms "LDAP" and "LDAPv3" are commonly used to informally refer 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-extension(s) is not defined by this document but may be
  defined in some future document(s).  Extensions are expected to be
  truly optional.

  IANA (Internet Assigned Numbers Authority) considerations for LDAP
  described in BCP 64 [BCP64bis] apply fully to this revision of the
  LDAP technical specification.

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
  X.500(1993) series of International Telecommunication Union - Telecom
  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, e.g. 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 is 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 [RFC3377]
  (which consists of RFC 2251-2256, RFC 2829-2830, RFC 3771, and RFC
  3377 itself).  The technical specification was significantly
  reorganized.

  This document replaces RFC 3377 as well as Section 3.3 of RFC 2251.
  [Models] replaces portions of RFC 2251, RFC 2252 and RFC 2256.
  [Protocol] replaces the majority RFC 2251, portions of RFC 2252, and
  all of RFC 3771.  [AuthMeth] replaces RFC 2829, RFC 2830, and portions
  of RFC 2251.  [Syntaxes] replaces the majority of RFC 2252 and
  portions of RFC 2256.  [Schema] replaces the majority of RFC 2256.
  [LDAPDN] replaces RFC 2253.  [Filters] replaces RFC 2254.  [LDAPURL]
  replaces RFC 2255.

  [LDAPprep] is new to this revision of the LDAP technical
  specification.

  Each document of this specification contains appendices summarizing
  changes to all sections of the specifications they replace.  Appendix
  A.1 of this document details changes made to RFC 3377.  Appendix A.2
  of this document details changes made to Section 3.3 of RFC 2251.

  Additionally, portions of this technical specification update and/or
  replace a number of other documents not listed above.  These
  relationships are discussed in the documents detailings these portions
  of this technical specification.


4. Security Considerations

  LDAP security considerations are discussed in each document comprising
  the technical specification.


5. IANA Considerations

Appendix A.  Changes to Previous Documents

  This appendix outlines changes this document makes relative to the
  documents it replaces (in whole or in part).


Appendix A.1. Changes to RFC 3377

  This document is nearly a complete rewrite of RFC 3377 as much of the
  material of RFC 3377 is no longer applicable.  The changes include
  redefining the terms "LDAP" and "LDAPv3" to refer to this revision of
  the technical specification.


Appendix A.2. Changes to Section 3.3 of RFC 2251

  The section was modified slightly (the word "document" was replaced
  with "technical specification") to clarify that it applies to the
  entire LDAP technical specification.
