Over on DevShed this morning, there's a duo of articles that you might want to check out - especially if you're working with PHP and LDAP.

In their two part article, Using PHP With LDAP part one and part two, they guide you through the world of LDAP, introducing you to what LDAP is, how it works, and how to get information out of it for your use. The second part of the series dives a little deeper, showing you how to create more complex queries with LDAP, and show you how to create a set of scripts that will let you add, edit, and delete information from the LDAP server.

I love how the author puts PHP and LDAP's relationship at the end of the article: Obviously, this is just the beginning - LDAP has a whole bunch of different applications, and PHP is well-suited to all of them. The synergy between the two technologies cannot be overemphasized, and, as the LDAP API in PHP evolves, you can expect to see more and more applications building on this synergy.

Thanks to Ewald for these links...
