Backport to UCS 4.4 +++ This bug was initially created as a clone of Bug #53674 +++ In handlers/__init__.py the hook "hook_ldap_pre_modify" is called after self._ldap_pre_modify(). In the case of the users/user module this has the consequence, that a user rename happens before the "hook_ldap_pre_modify" has a chance to intervene in any way.
