[horde] Passwd Module - LDAP error, fixed

[Andy Dorman]

As it turns out, at least for my case...setting the userdn is not 
necessary because code in /passwd/lib/Driver/Ldap.php->_changePassword 
is supposed to build a userdn if one does not exist.

However, _changePassword accepts $user for input and then goes on to use 
$username to build the userdn.  Whoops.  An easy mixup and a simple fix.

I have submitted a ticket to fix that particular bug.

Now to see if I can figure out how to deal with the crash that happens 
after successfully changing my password.  ;-)
