LDAP
The Lightweight Directory Access Protocol (LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number. LDAP is specified in a series of Internet Engineering Task Force (IETF) Standard Track publications called Request for Comments (RFCs), using the description language ASN.1. The latest specification is Version 3, published aRFC 4511ref name="gracion Gracion.com. Retrieved on 2013-07-17. (a road map to the ...

Directory Service
In computing, a directory service or name service maps the names of network resources to their respective network addresses. It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects. A directory service is a critical component of a network operating system. A directory server or name server is a server which provides such a service. Each resource on the network is considered an object by the directory server. Information about a particular resource is stored as a collection of attributes associated with that resource or object. A directory service defines a namespace for the network. The namespace is used to assign a ''name'' (unique identifier) to each of the objects. Directories typically have a set of rules determining how network resources are named and identified, which usually includes a ...

Directory Service Markup Language
Directory Services Markup Language (DSML) is a representation of directory service information in an XML syntax. The DSML version 1 effort was announced on July 12, 1999 by creator Bowstreet (subsequently acquired by IBM in 2005). Initiative supporters include AOL-Netscape, Sun Microsystems, Oracle, Novell, Microsoft, and IBM. It resulted in a Document Type Definition for a file containing the XML representation of entries in the LDAP data model, similar in spirit to LDIF. The DSML version 2 effort was promulgated in OASIS in 2001. It resulted in an XML schema for the representation of directory access operations based on that of LDAP, that could be carried in SOAP Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products.

XML Enabled Directory
XML Enabled Directory (XED) is a framework for managing objects represented using the Extensible Markup Language (XML). XED builds on X.500 and LDAP directory services technologies. XED was originally designed in 2003 by Steven Legg of (formerly of eB2Bcom and Adacel Technologies) and Daniel Prager (formerly of Deakin University Deakin University is a public university in Victoria, Australia. Founded in 1974, the university was named after Alfred Deakin, the second Prime Minister of Australia. Its main campuses are in Melbourne's Burwood suburb, Geelong Waurn Ponds, ...). The XML Enabled Directory (XED) framework leverages existing Lightweight Directory Access Protocol (LDAP) and X.500 directory technology to create a directory service that stores, manages and transmits Extensible Markup Language (XML) format data, while maintaining interoperability with LDAP clients, X.500 Directory User Agents (DUAs), and X.500 Directory System Agents (DSAs).

Colin Robbins (software Engineer)
Colin Robbins (born 1964) is a network protocol and software engineer credited for research work in distributed directory systems and a co-inventor of LDAP. Educated at Alleyn's School, he holds a BSc, Computer Science & Electronic Engineering, with first class honours, from University College London. Robbins developed the Quipu directory part of the ISO Development Environment (ISODE) while a research assistant at UCL working for Peter Kirstein, he became custodian of ISODE from Marshall Rose in 1991. Quipu was used to prototype DIXIE and DASED, which merged to invent LDAP of which Robbins wrote the ''String Representation of Standard Attribute Syntaxes'' element defined in RFCs 1448 and 1778 published by the IETF. Robbins wrote part 3 of Steve Kille's book ''Implementing X.400 and X.500: the PP and QUIPU Systems''.

Abstract Syntax Notation One
Abstract Syntax Notation One (ASN.1) is a standard interface description language for defining data structures that can be serialized and deserialized in a cross-platform way. It is broadly used in telecommunications and computer networking, and especially in cryptography. Protocol developers define data structures in ASN.1 modules, which are generally a section of a broader standards document written in the ASN.1 language. The advantage is that the ASN.1 description of the data encoding is independent of a particular computer or programming language. Because ASN.1 is both human-readable and machine-readable, an ASN.1 compiler can compile modules into libraries of code, codecs, that decode or encode the data structures. Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and ISO/ IEC, o ...

Directory Assistance Service
The Directory Assistance Service (DAS) is an obsolete protocol and service for accessing X.500 directory services. DAS was intended to provide a lightweight means for clients to access X.500 directory services via a split-Directory User Agent model. Here, the Directory User Agent (DUA) (the directory client) is split into a Directory Assistance (DA) client and a Directory Assistant. The directory user would interact with the DA-client, the DA-Client would communicate with the Directory Assistant using the DA protocol, and the Directory Assistant would communicate with the Directory Service using the X.500 Directory Access Protocol (DAP). That is, the Directory Assistant is a Directory Assistance protocol to DAP gateway. This design allows the DA-client to access the directory without requiring it to support the cumbersome Open Systems Interconnection protocol stack. The Directory Assistance Service was created in 1990 by Marshall Rose while at Performance Systems International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Authentication And Security Layer
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also support ''proxy authorization'', a facility allowing one user to assume the identity of another. They can also provide a ''data security layer'' offering ''data integrity'' and ''data confidentiality'' services. DIGEST-MD5 provides an example of mechanisms which can provide a data-security layer. Application protocols that support SASL typically also support Transport Layer Security (TLS) to complement the services offered by SASL. John Gardiner Myers wrote the original SASL specification (RFC 2222) in 1997. In 2006, that document was replaced by RFC 4422 authored by Alexey Melnikov and Kurt D. Zeilenga. SASL, as defined by RFC 4422 is an IETF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simu ...
