We have recently turned on full debugging in our TEST environment and found the warning message prevents redirection:

Warning: ldap_search(): Search: No such object in /var/www/moodle/lib/ldaplib.php on line 241

Warning: ldap_first_entry() expects parameter 2 to be resource, boolean given in /var/www/moodle/lib/ldaplib.php on line 248

has a non-specific relationship to
