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.
