In reality (Score 2, Insightful)

In reality this book is meant to be for LDAP beginners and Tom does make that clear. I believe the book was actually originally written as a college text which further strengthens the point is geared for a beginner. Having a actual paperback book on man pages and scripting examples is probably one of the most lacking pieces of documentation around for LDAP. The only good docs I've found on Net::LDAP and even the php libraries are only the authors api docs. The truth is you need scripting examples to get good at managing LDAP.
