Active Directory (AD) is a database and set of services that connect users with the network resources they need to get their work done.
The database (or directory) contains critical information about your environment, including what users and computers there are and who’s allowed to do what. For example, the database might list 100 user accounts with details like each person’s job title, phone number and password. It will also record their permissions.
The services control much of the activity that goes on in your IT environment. In particular, they make sure each person is who they claim to be (authentication), usually by checking the user ID and password they enter, and allow them to access only the data they’re allowed to use (authorization).
