Distinguished Name
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 req ...

DIXIE
Dixie, also known as Dixieland or Dixie's Land, is a nickname for all or part of the Southern United States. While there is no official definition of this region (and the included areas shift over the years), or the extent of the area it covers, most definitions include the U.S. states below the Mason–Dixon line that seceded and comprised the Confederate States of America, almost always including the Deep South. The term became popularized throughout the United States by songs that nostalgically referred to the American South. Region Geographically, ''Dixie'' usually means the eleven Southern states that seceded from the United States of America in late 1860 and early 1861 to form the Confederate States of America. They are listed below in order of secession: #South Carolina #Mississippi #Florida #Alabama #Georgia #Louisiana #Texas #Virginia #Arkansas #North Carolina #Tennessee Although Maryland is rarely considered part of Dixie today, it is below the Mason–Dixon lin ...

Service Location Protocol
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. It has been defined in RFC 2608 and RFC 3224 as standards track document. Overview SLP is used by devices to announce ''services'' on a local network. Each service must have a URL that is used to locate the service. Additionally it may have an unlimited number of name/value pairs, called ''attributes''. Each device must always be in one or more ''scopes''. Scopes are simple strings and are used to group services, comparable to the ''network neighborhood'' in other systems. A device cannot see services that are in different scopes. The URL of a printer could look like: service:printer:lpr://myprinter/myqueue This URL describes a queue called "myqueue" on a printer with the host name "myprinter". The proto ...

Service Provisioning Markup Language
Service Provisioning Markup Language (SPML) is an XML-based framework, being developed by OASIS, for exchanging user, resource and service provisioning information between cooperating organizations. The Service Provisioning Markup language is the open standard for the integration and interoperation of service provisioning requests. SPML is an OASIS standard based on the concepts of 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 su .... SPML version 1.0 was approved in October 2003.

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).

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] |
