  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.

  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
  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: Directory Information Models [Models],
      LDAP: The Protocol [Protocol],
      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 [Syntaxes], 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
  protocol suite, as defined here, should be formally identified in
  other documents by a normative reference to this document.

  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).

  IANA considerations for LDAP [LDAPIANA] 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 ITU 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 model as
  used in LDAP is not violated in the LDAP interface.

3. Security Considerations

INTERNET-DRAFT        draft-ietf-ldapbis-roadmap-00     21 February 2002

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

4. Relationship to Obsolete Specifications

  This technical specification, as defined in Section 1, obsoletes
  entirely the previously defined LDAP technical specification [LDAPTS]
  (which consists of RFC 2251-2256, RFC 2829-2830 and [LDAPTS] itself).
  The technical specification was significantly reorganized.

  This document replaces replaces [LDAPTS] 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 and portions of RFC 2252.
  [AuthMeth] replaces RFC 2829, RFC 2830, and portions of RFC 2251.
  [Syntax] 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.

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

5. Acknowledgments

  This document is based largely on [LDAPTS] by J. Hodges and R.
  Morgan, a product of the LDAP Extensions Working Group.  The document
  also borrows from [RFC2251] by M. Wahl, T. Howes, and S. Kille, a
  product of the ASID Working Group.

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

Appendix A.1. Changes to [LDAPTS]

  This document is nearly a complete rewrite of [LDAPTS] as much of the
  material of [LDAPTS] is no longer applicable.  These changes include
  defining the term "LDAP" in addition to "LDAPv3" and using "LDAP" in
  favor of "LDAPv3" for consistency with the remainder of the technical

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.
