Thank you very much for your reply!

Your code didn't work "as is" for me but it was a good starting point. I 
mixed a bit of your code with the hooks.php.dist sample and got it 
working. Here is the code that did the trick for future reference.

The piece of code that just wasn't working is the findUserDN method 
which reported the following exception
> exception 'Horde_Exception_NotFound' with message 'Could not fetch entry userPrincipalName=dwells at fliawells.com.ar: no entry found' in /usr/lib64/php/Horde/Ldap.php:1080

If someone could help me figure out what could be wrong with this I 
would appreciate it but at least I can go on with this task.

Thank you very much again!
