INTERNET-DRAFT draft-ietf-ldapbis-roadmap-07 10 February 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. Security Considerations
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 [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
Zeilenga LDAP: TS Road Map [Page 3]
INTERNET-DRAFT draft-ietf-ldapbis-roadmap-07 10 February 2005
replace a number of other documents not listed above. These
relationships are discussed in the documents detailings these portions
of this technical specification.

INTERNET-DRAFT draft-ietf-ldapbis-roadmap-07 10 February 2005
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.
