Subject: Ticket 47958 - Memory leak in password admin if the admin entry does not exist


Bug Description:  If passwordAdminDN is set to an entry that does not exist memory
                  is leaked.

Fix Description:  The leak occurs because we do not free the internal search results,
                  even when zero entries are returned.
