Simplify access to networked resources.
Active Directory (AD) consists of several services to manage permissions and access to networked resources on Windows-based products. The main service in Active Directory is Domain Services, which stores directory information and handles the interaction of the user with the domain. AD DS verifies access when a user signs into a device or attempts to connect to a server over a network. AD DS controls which users have access to each resource. For example, an administrator typically has a different level of access to data than an end user.
Several other services comprise AD. They are Lightweight Directory Services, Certificate Services, Federation Services and Rights Management Services. Each service expands the product’s directory management capabilities.
