Centralize user accounts with OpenLDAP
Building a centralized authentication system using Lightweight Directory Access Protocol (LDAP) promises to reduce administration costs, increase security, avoid data replication, and increase data consistency. As Linux® has matured, better tools have emerged to ease the migration of user account information into an LDAP directory. Tools have also been developed to enable the configuration of encrypted communication between a client and the directory server and to provide fault tolerance through replication. This article shows you how to configure a server and client to use OpenLDAP on Red Hat Linux.
