Abstract:

The implementation and exploitation of centralized, corporate-wide directories are among the top priority projects in most organizations. The need for a centralized directory emerges as organizations realize the overhead and cost involved in managing the many distributed micro and macro directories introduced in the past decade with decentralized client/server applications and network operating systems. This IBM Redbook will help you create a foundation of LDAP skills, as well as install and configure the IBM Directory Server. It is targeted at security architects and specialists who need to know the concepts and the detailed instructions for a successful LDAP implementation.
