Centrify DirectControl extends Microsoft Active Directory's identity management, access control and Group Policy services to Unix, Linux, Java and web platforms. DirectControl turns Unix/Linux systems into Active Directory clients, enabling you to move to a single point of administration, establish single sign-on, and apply global password and other security policies. DirectControl is the only solution that can integrate multiple Unix/Linux profiles and identities into Active Directory without intrusive changes to existing systems.
