	Lightweight Directory Access Protocol - Wikipedia, the free encyclopedia
		The protocol was authored by Tim Howes of Netscape, Steve Kille of ISODE and Mark Wahl of Critical Angle Inc.
		Directories such as OpenLDAP and its predecessors from the University of Michigan, though primarily designed as native repositories optimized for access by LDAP rather than as a gateway to X.500 protocols as was provided in ISODE, are nevertheless no more "LDAP directories" than any other directory accessible by the LDAP protocol.
		An LDAP directory entry consists of a collection of attributes and is referenced unambiguously with a name, called a distinguished name (DN).

	RFC 1777 (rfc1777) - Lightweight Directory Access Protocol (Site not responding. Last check: 2007-10-06)
		This protocol makes no provisions for the return of referrals to clients, as the model is one of servers ensuring the performance of all necessary operations in the Directory, with only final results or errors being returned by servers to clients.
		In the event that a protocol implementation encounters an Attribute Type with which it cannot associate a textual string, an ASCII string encoding of the object identifier associated with the Attribute Type may be subsitituted.
		Protocol Element Encodings The protocol elements of LDAP are encoded for exchange using the Basic Encoding Rules (BER) [12] of ASN.1 [11].

		In keeping with the goal of easing the costs associated with use of the directory, it is an objective of this protocol to minimize the complexity of clients so as to facilitate widespread deployment of applications capable of using the directory.
		Elements of Protocol The LDAP protocol is described using Abstract Syntax Notation 1 (ASN.1) [3], and is typically transferred using a subset of ASN.1 Basic Encoding Rules [11].
		An X.501(1993) Matching Rule is identified in the LDAP protocol by the printable representation of its OBJECT IDENTIFIER, either as one of the strings given in [5], or as decimal digits with components separated by periods, e.g.

	Lightweight Directory Access Protocol
		The Lightweight Directory Access Protocol (LDAP) is a lightweight version of the Directory Access Protocol, which is part of X.500.
		Being neither a directory nor a database, LDAP is an access protocol that defines operations for how clients can access and update data in a directory environment.
		LDAP is an important protocol to IP networking and is therefore important to the development and administration of mobile data applications.

	Introduction to Lightweight Directory Access Protocol (LDAP)
		The Directory Access Protocol (DAP) is a protocol used in X.500 Directory Services for controlling communications between the DUA and DSA agents.
		Directory services can be used to provide global, unified naming service for all elements in a network, translate between network names and addresses, provide descriptions of objects in a directory, and provide unique names for all objects in the Directory.
		Lightweight protocols use various measures and refinements to streamline and speed up transmissions, such as using connection-oriented transmissions, such as (TCP/IP) and a fixed header and trailer size to save the overhead of transmitting a destination address with each packet.

	EBN - Lightweight Directory Access Protocol (Site not responding. Last check: 2007-10-06)
		Researchers at the University of Michigan conceived LDAP as a simplified replacement for X.500's native access protocol, known as the Directory Access Protocol.
		An X.500 directory could be run on a mainframe, minicomputer, or other high-horsepower machine, while individuals with PCs and other computationally challenged machines could use LDAP to access the directory.
		The goal of a directory is to keep track of some entity, which might be a person, but could also be a printer or other resource, and to store relevant and needed information about that entity.

		The LDAP protocol is usually used as a central authentication server, so that the users have a unified connection that ensures connection from terminals, POP servers, IMAP (Internet Message Access Protocol) server, computers running under Samba connected to the network and computers Windows NT.
		The fact that entries in a directory are stored hierarchically, and that access controls can be applied to sub-trees of entries (as well as to individual entries and entry attributes) means that representing and securing data comes very naturally to a directory.
		Active Directory acts as the central authority for network security, letting the operating system readily verify a user's identity and control his or her access to network resources.

	Introduction to LDAP (Lightweight Directory Access Protocol) (Site not responding. Last check: 2007-10-06)
		Directory servers are applications that primarily act as directory services, providing information from a directory to other applications or end users.
		With a relatively simple replication model and access protocol, as well as the ability to discover servers on a local network, its creation was necessary due to the growth in client-server computing where users might exist on a number of servers.
		The protocol was relatively simple and text-based; it was easy to access programmatically but designed to run on a central server, limiting its scalability and scope.

		Because DAP is too heavyweight and difficult to easily implement, the University of Michigan, with help from the ISODE Consortium, designed and developed LDAP.
		LDAP is a protocol that defines a directory service and the access to that service.
		This means that it lacks some of DAP's functionality, but it also means that PCs and Macintoshes can run the LDAP protocol to access and manipulate X.500 directory services.

		These directories can store a variety of information and can even be used in a manner similar to Network Information Service (NIS), enabling anyone to access their account from any machine on the LDAP enabled network.
		But LDAP is more flexible than a traditional phone directory, because it is capable of referring a querent to other LDAP servers throughout the world, providing an ad-hoc global repository of information.
		If the client application is attempting to modify information an LDAP directory, the server verifies that the user has permission to make the change and then adds or updates the information.

		The protocol is known as "DAP" (Directory Access Protocol).
		The major difference is that the LDAP protocol itself is designed to run directly over the TCP/IP stack, and it lacks some of the more esoteric DAP protocol functions.
		It is the technical counterpart to the "Lightweight Directory Access Protocl: X.500 Lite" paper referenced above, and denotes version 2 of the LDAP protocol (LDAPv2).

		Active Directory implements the LDAP attribute draft specifications and the IETF standards for LDAP versions 2 and 3.

	X.500: Directory Access Protocol (DAP) Overview
		X.500, the directory Access Protocol (DAP) by ITU-T (X.500) and also ISO (ISO/IEC 9594), is a standard way to develop an electronic directory of people in an organization so that it can be part of a global directory available to anyone in the world with Internet access.
		This is done in such a way that an end user can access information in the Directory without needing to know the exact location of that specific piece of information.
		Standards-Based Directory Services: As X.500 can be used to build a standards-based directory, applications which require directory information (e-mail, automated resources locators, special-purpose directory tools) can access a planet's worth of information in a uniform manner.
