This IBM Redbooks publication will help system administrators and programmers to understand the concepts of directories. It also explains the major steps in planning and deploying a directory.

You will learn how to install and configure OS/400 Directory Services with all its features provided with OS/400 Version 5 Release 1. The implementation topics also teach you how to improve availability and scalability by exploiting directory replication and referral services. In a world where security is a key factor in establishing a reliable IT infrastructure, you also gain the skills to enable your LDAP directory server and client applications to securely communicate via the SSL protocol.

The book continues with detailed information about how to successfully manage your directory. This includes various tools, such as the IBM SecureWay Directory Management Tool and LDAP utilities. Detailed information is provided on how to secure your directory entries and their attributes using the Version 5 Release 1 attribute-level permission enhancements.

Based on a practical scenario that spans across the entire book, you will learn how to leverage OS/400 LDAP Directory Services to authenticate users and share configuration information with the IBM HTTP server for iSeries. You discover how Lotus Domino and WebSphere Application Server 4.0 exploit the OS/400 LDAP directory for Single Sign-On. Using the directory as an enterprise directory, you gain the knowledge to configure various e-mail client applications to look up e-mail addresses from a single directory. The book also describes how to directory-enable your applications using OS/400 APIs and the Java Naming and Directory Interface (JNDI).
