 I've updated the branch toward this direction, but not completely
 deprecated WILDCARD_xxx as it would require rather big changes to the
 existing database data source implementation.  For now, I introduced a
 quick hack wrapper in the auth Query code to convert the old format to
 the new one.

 If this approach is okay I'll create a separate ticket for the
 subsequent refactoring.
