![]() The LDAP concept began to emerge even before the founding of Microsoft in April 1975, with RFCs as early as 1971. Also, X.500 directories and the Organizational Unit preceded the Active Directory concept that makes use of those methods. For example, LDAP underpins Active Directory. The Internet Engineering Task Force (IETF), which oversees the RFC process, has accepted numerous RFCs initiated by widespread participants. ![]() Like many information-technology efforts, Active Directory originated out of a democratization of design using Request for Comments (RFCs). The domain database is, in effect, Active Directory." History ![]() That database holds records about network services-things like computers, users, groups and other things that use, support, or exist on a network. Īctive Directory uses Lightweight Directory Access Protocol (LDAP) versions 2 and 3, Microsoft's version of Kerberos, and DNS. Also, it allows management and storage of information, provides authentication and authorization mechanisms and establishes a framework to deploy other related services: Certificate Services, Active Directory Federation Services, Lightweight Directory Services, and Rights Management Services. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted username and password and determines whether the user is a system administrator or normal user. It authenticates and authorizes all users and computers in a Windows domain type network, assigning and enforcing security policies for all computers, and installing or updating software. Ī server running the Active Directory Domain Service ( AD DS) role is called a domain controller. However, Active Directory eventually became an umbrella title for a broad range of directory-based identity-related services. Initially, Active Directory was used only for centralized domain management. It is included in most Windows Server operating systems as a set of processes and services. Not to be confused with Microsoft Azure Active Directory.Īctive Directory ( AD) is a directory service developed by Microsoft for Windows domain networks.
