<pre>Author/s : Clayton Donley Publisher : Manning Category :Miscellaneous Java Review by : Michael Ernest Rating : 8 horseshoes</pre> Author Clayton Donley has been intimately involved with LDAP for a long time. This book bears many qualities you would hope for from such an expert: the background of LDAP given is concise and helpful. He also lends some understanding to seemingly arbitrary features or technologies that have been included with LDAP over the years. The reader will need to understand or learn much more than Java programming to work through the entire book, however. Accessing an LDAP directory through JNDI covers most of the Java subject matter. There's much more administration-oriented code illustrated in Perl. Directory Services Markup Language (DSML), an XML-based protocol is also discussed as well as requisite coverage on LDAP Data Interchange Format (LDIF). Like many books on directory servers, Donley's is best used by readers who need a clearer, more up-to-date guide on LDAP than the book they've been using. As simple as the goals of LDAP-based systems are, it's often difficult to reconcile simple goals with the complex web of technologies used to exoress them.
