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.
