Mastering OpenLDAP: Configuring, Securing and Integrating Directory Services by Matt Butcher

This book has been written from the application developers perspective, tackling the topics that will be most important to helping the application developer understand OpenLDAP, and get it set up as securely and quickly as possible. It shows how OpenLDAP interoperates with other UNIX/Linux services (DNS, NIS, Samba, etc.). The target audience will require basic Linux system administration knowledge, but no prior knowledge of LDAP or OpenLDAP is assumed. If you are web savvy and are interested in using OpenLDAP for web applications and services like client interaction then this is the book for you.
