A server running Active Directory Domain Services (AD DS) is named a website controller. It authenticates and authorizes all users and computers in a very Windows domain sort network—assigning and implementing security policies for all computers and putting in or change package. For instance, once a user logs into a laptop that’s a part of a Windows domain, Active Directory checks the submitted countersign and determines whether or not the user may be a supervisor or traditional user. Also, it permits management and storage of data, provides authentication and authorization mechanisms and establishes a framework to deploy alternative connected services: Certificate Services, federate Services, light-weight Directory Services, and Rights Management Services.
