Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. [1] [2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity ...
The Relative ID Master allocates security RIDs to Domain Controllers to assign to new Active Directory security principals (users, groups or computer objects). It also manages objects moving between domains. The Relative ID Master is one role of the Flexible single master operation for assigning RID.
Computers can connect to a domain via LAN, WAN or using a VPN connection. Users of a domain are able to use enhanced security for their VPN connection due to the support for a certification authority which is gained when a domain is added to a network, and as a result, smart cards and digital certificates can be used to confirm identities and protect stored information.
It authenticates users, stores user account information and enforces security policy for a domain. [3] It is most commonly implemented in Microsoft Windows environments (see Domain controller (Windows)), where it is the centerpiece of the Windows Active Directory service.
Security Identifier (SID) is a unique, immutable identifier of a user account, user group, or other security principal in the Windows NT family of operating systems. A security principal has a single SID for life (in a given Windows domain), and all properties of the principal, including its name, are associated with the SID.
AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource ...
In ADFS, identity federation [4] is established between two organizations by establishing trust between two security realms. A federation server on one side (the accounts side) authenticates the user through the standard means in Active Directory Domain Services and then issues a token containing a series of claims about the user, including their identity.
Windows Vista and later Windows versions allow individual group policies per user accounts. [6] Site - Any Group Policies associated with the Active Directory site in which the computer resides. (An Active Directory site is a logical grouping of computers, intended to facilitate management of those computers based on their physical proximity.)
