Active directory is a network technology that provides a variety of network services. The services include: Directory services: these services provide every user with a home directory. The user can store his/her files on it, can install software etc. Each user’s directory will be protected by a user name and password. Authentication services: Active directory comes with Kerberos based authentication services. These services can be used for checking of various user name and passwords for various applications.
