Lightweight Directory Access Protocol (LDAP) is now a staple of enterprise and Internet software environments. Anyone involved with Internet development, where Java(TM) technology is prominent, or in enterprise information systems must understand how to use Java technology--especially the Directory SDK for Java--in order to unlock the power of LDAP. <P> Written by the designer of the Directory SDK for Java and by a leading implementor of directory-based solutions," LDAP Programming with Java(TM)" is the first accurate, concise, and complete guide on accessing LDAP from Java applications. Assuming familiarity with Java programming, the book provides a comprehensive discussion of LDAP, from basic directory concepts to the most advanced techniques. It collects in one convenient resource the many innovative and experience-based techniques and approaches programmers have discovered for using the Directory SDK to solve LDAP access challenges. <P> If you are new to LDAP, you will find helpful background information about the role of directories in today's software systems; LDAP methods of storing, accessing, searching, and updating data; and how the Directory SDK for Java helps applications gain access to an LDAP server. Once you have become proficient with the essential concepts and techniques, you can move on to detailed material about authentication, LDAP and JavaScript(TM), working with JavaBeans(TM) for reusable LDAP components, expressing data relationships in a directory, and other advanced LDAP subjects. <P> Specific topics covered include: <LI>The LDAP naming and information models <LI>The command-line tools of the SDK <LI>Authentication with a password, SSL, and SASL<LI>Configuring access control <LI>Writing LDAP applets for a browser <LI>Accessing the SDK from JavaScript <LI>Storing configuration and preferences in a directory <LI>Encapsulating LDAP functionality in a JavaBean <LI>Using LDAP in Java servlets <LI>LDAP URLs <LI>Multiple threads and mu

This guide to accessing the lightweight directory access protocol (LDAP) from Java applications provides experienced Java programmers with techniques for using the Directory SDK to solve LDAP access challenges. Advanced topics include authentication, working with JavaBeans for reusable LDAP components, and expressing data relationships in a directory. The CD-ROM contains source code for the Directory SDK and examples.

In this book, the creators of the Directory SDK for Java show how it can be used to build powerful, standards-based directory applications that leverage LDAP directory information on intranets, the Internet, even in e-commerce applications. The CD-ROM includes reference documentation and source code for the Directory SDK for Java and for all examples and programs in the book, as well as the entire text of the book in a fully searchable format.
