Can change RDN only after small patch

A comment in line 299 of ldapprov.module says

 // The user name in $form['_account']['#value'] is already changed.
// Has to look for the old name in the authmap.

which is not correct in my case. The following if() fails and a user update is not done.

Changing the if to

if (isset($values['name']) && ($row = db_fetch_object($result)) && $values['name'] != $row->authname)
solves the problem.
