Directory server

Windows domains require directory servers to store the Active Directory.

Active Directory, the directory service central to the Windows Server operating system, runs only on domain controllers. Active Directory is a LDAP-based directory system capable of storing the information about large numbers of users and providing rapid access to applications.

In addition to providing a place to store data and services to make that data available, Active Directory protects network objects from unauthorized access and replicates objects across the network so that data is not lost if one domain controller fails.

CIC can use Windows Active Directory services to authenticate users.
