Scalable Centralized Authentication Services Using Red Hat Directory Server
Source: Red Hat
The Red Hat Directory Server provides a scalable method for Centralized Authorization and Authentication services to a large enterprise. The netgroup feature provided by the Directory Server provides a way to group users and systems into different groups. By configuring pam to use these groups, it can implement user access control enterprise wide with minimal changes to the systems. Since the user, system, and group information are stored centrally at the Directory Server, the information is secure and updates are instantaneous and enterprise wide. By eliminating system and user specific information (except the network configuration) on the systems, system deployment is simplified by creating standard images. Further, addition, deletion and role change of users or systems is greatly simplified.
