Windows Server: Active Directory

 

Active Directory is a database that contains track of all the user accounts and passwords in your organization. It allows you to store your user accounts and passwords in one protected location, improving your organization’s security including all user details.

 

Active Directory helps to manage the identities and relationships that build your organization’s network. Integrated with Windows Server, Active Directory gives you much functionality needed to centrally configure and administer system, user, and application settings.
