Care of PHP Magazine, there's a pointer to a new article over on Developer.com dealing with the integration of Active Directory with PHP.

Within this and the coming articles, I'll highlight key concepts pertinent to implementing services requiring Active Directory/PHP/Perl/Apache integration. I'll assume that you're already familiar with basic Active Directory data schemas, in addition to general LDAP syntax.

Furthermore, I'll take for granted that you're familiar with PHP and Perl language syntax, and with Apache's configuration syntax. Finally, because administration-level changes could be necessary, you'll need privileged control, or at least the administrator's willingness to made changes for you.

He starts off by identifying some of the key functions that you'll need to make the connection (LDAP) and explains how to use each. From there, he creates a sample form to just search based on one term, go out to the server, and grab the results to display them. It's simple and procedural, but it's a start....keep your eye out for more in this series.
