Directory Service

Directory Services Markup Language 1 'Directory Services Markup Language' (DSML) is a representation of directory service information in an XML syntax.

Multi-master replication - Directory services 1 Many directory service|directory servers based on Lightweight Directory Access Protocol|LDAP implement multi-master replication.

Novell Directory Services 1 'Novell eDirectory' (formerly known as Novell Directory Services, sometimes referred to as Netware Directory Services) is an X.500-compatible directory service software product initially released in 1993 by Novell for centrally managing access to resources on multiple Server (computing)|servers and computers within a given computer network|network

Directory service 1 A 'directory service' is the software system that stores, organizes and provides access to information in a directory

Directory service 1 Many different directory services have been used since the advent of the Internet but this article focuses mainly on those that have descended from the X.500 directory service.

Directory service - Introduction 1 A directory service called a naming service, maps the names of network resources to their respective network addresses

Directory service - Introduction 1 In X.500 (the directory service standards) and Lightweight Directory Access Protocol|LDAP the name is called the 'Distinguished name' (DN) and is used to refer to a collection of attributes (relative distinguished names) which make up the name of a directory entry.

Directory service - Introduction 1 For example, looking up computers using a directory service might yield a list of available computers and information for accessing them.

Directory service - Introduction 1 The term distribution is used to indicate that multiple directory servers, that hold different namespaces, are interconnected to form a distributed directory service

Directory service - Comparison with relational databases 1 There are a number of things that distinguish a traditional directory service from a typical relational database. Of course there are exceptions, but in general:

Directory service - Comparison with relational databases 1 * Directory services are often a central component in the Computer security|security design of an IT system and have a correspondingly fine granularity regarding access control: who may operate in which manner on what information. Also see: Access control list|ACLs

Directory service - Implementations of directory services 1 In the 1980s, the International Telecommunication Union|ITU and International Organization for Standardization|ISO came up with a set of standards - X.500, for directory services, initially to support the requirements of inter-carrier electronic messaging and network name lookup

Directory service - Implementations of directory services 1 There have been numerous forms of directory service implementations from different vendors. Systems developed before the advent of X.500 include:

Directory service - Implementations of directory services 1 * 'Domain Name System:' (DNS), the first directory service on the Internet, which is still used everywhere today.

Directory service - Implementations of directory services 1 * 'Network Information Service:' (NIS), originally named Yellow Pages (computing)|Yellow Pages (YP), was Sun Microsystems' implementation of a directory service for Unix network environments. It served a similar role as Hesiod.

Directory service - Implementations of directory services 1 * 'NetInfo:' was developed by NeXT in the late 1980s for NEXTSTEP. After being acquired by Apple, it was released as open source and used as the directory service for Mac OS X before being deprecated in favor of the LDAP-based Open Directory. Support for NetInfo was completely removed with the release of 10.5 Leopard.

Directory service - Implementations of directory services 1 * 'Windows domain|NT Domains:' was developed by Microsoft to provide directory services for Windows machines prior to the release the LDAP-based Active Directory in Windows Windows Vista continues to support NT Domains, but only after relaxing the minimum authentication protocols it supports.

Directory service - LDAP implementations 1 * 'Active Directory:' Microsoft's modern directory service for Windows, originating from the X.500 directory, created for use in Exchange Server, first shipped with Windows 2000 Server and is supported by successive versions of Windows.

Directory service - LDAP implementations 1 * 'Novell eDirectory|eDirectory:' This is Novell's implementation of directory services. It supports multiple architectures including Microsoft Windows|Windows, NetWare, Linux and several flavours of Unix and has long been used for user administration, configuration management, and software management. eDirectory has evolved into a central component in a broader range of Identity management products. It was previously known as Novell Directory Services.

Directory service - LDAP implementations 1 * 'Red Hat Directory Server:' Red Hat released a directory service, that it acquired from AOL's 'Netscape Security Solutions' unit,[ wArticle.jhtml?articleID= ] as a commercial product running on top of Red Hat Enterprise Linux called Red Hat Directory Server and as the community supported 389 Directory Server project.

Directory service - LDAP implementations 1 * 'Open Directory:' Apple Computer|Apple's Mac OS X Server uses a directory service named Apple Open Directory|Open Directory, which implements Lightweight Directory Access Protocol|LDAP using a customized build of OpenLDAP and integrates support for both Simple Authentication and Security Layer|SASL and Kerberos (protocol)|Kerberos authentication. It uses a plugins architecture to work with other LDAPv3 directories, including proprietary solutions like Active Directory and eDirectory.

Directory service - LDAP implementations 1 * 'Apache Directory Server:' Apache Software Foundation offers a directory service called Apache Directory Server|ApacheDS.

Directory service - LDAP implementations 1 * 'Sun Java System Directory Server:' Sun Microsystems' current directory service offering

Directory service - LDAP implementations 1 * 'OpenDS:' An open source directory service implementation from scratch in Java, backed by Sun Microsystems

Directory service - LDAP implementations 1 There are also plenty of open-source tools to create directory services, including OpenLDAP and the Kerberos (protocol)|Kerberos protocol, and Samba software which can act as a Windows Domain Controller with Kerberos (protocol)|Kerberos and LDAP backends. Administration is done using GOsa or Samba provided Samba software|SWAT.

Directory services 1 As a word in a dictionary may have multiple definitions, a directory service can associate a name with multiple, different pieces of information

Directory services - Introduction 1 A directory service called a naming service, maps the names of network resources to their respective network addresses

Directory services - Comparison with relational databases 1 Several things distinguish a traditional directory service from a typical relational database. Of course there are exceptions, but in general:

Directory services - LDAP implementations 1 * 'Apache Directory Server:' Directory service written in Java, supporting LDAP, Kerberos 5 and the Change Password Protocol. LDAPv3 certified. The Apache Directory Server is also a top level project of the Apache Software Foundation.

Directory services - LDAP implementations 1 * 'NetIQ eDirectory|eDirectory:' This is NetIQ's implementation of directory services. It supports multiple architectures including Microsoft Windows|Windows, NetWare, Linux and several flavours of Unix and has long been used for user administration, configuration management, and software management. eDirectory has evolved into a central component in a broader range of Identity management products. It was previously known as Novell Directory Services.

Directory Services Restore Mode 1 'Directory Services Restore Mode' (DSRM) is used on a Microsoft Windows Domain Controller to take the Active Directory on that machine offline.

Novell Directory Service 1 Previously owned by Novell, the product has also been known as 'Novell Directory Services' ('NDS') and sometimes referred to as NetWare Directory Services

Novell Directory Service - Features 1 The software supports referential integrity, multi-master replication, and has a modular authentication architecture. It can be accessed via Lightweight Directory Access Protocol|LDAP, Directory Service Markup Language|DSML, SOAP, ODBC, JDBC, JNDI, and Active Directory Service Interfaces|ADSI.

NT Directory Service 1 'Active Directory' ('AD') is a directory service that Microsoft developed for Windows domain networks and is included in most Windows Server operating systems as a set of Process (computing)|processes and Windows service|services.

NT Directory Service - Logical structure 1 As a directory service, an Active Directory instance consists of a database and corresponding executable code responsible for servicing requests and maintaining the database

NT Directory Service - Database 1 Programs may access the features of Active Directory via the Component Object Model|COM interfaces provided by Active Directory Service Interfaces.

NT Directory Service - Database 1 [ us/library/aa772170%28VS.85%29.aspx Active Directory Service Interfaces], Microsoft

NT Directory Service - Unix integration 1 An alternate option is to use another directory service such as 389 Directory Server (formerly Fedora Directory Server, FDS), ViewDS Identity Solutions - ViewDS v7.2 XML Enabled Directory or Sun Microsystems Sun Java System Directory Server, with the latter two both being able to perform two-way synchronization with AD and thus provide a deflected integration, as non-Windows clients authenticate to this while Windows Clients authenticate to AD
