Filters on dname syntax attributes do not work (e.g documentdn in the
samples). In the traces, we can see that the generated SQL request
contains ...AND ldap_entries.oc_map_id = 1 AND ldap_entries.oc_map_id =
2... (1 being the person object id and 2 being the document object id).
[Pierangelo Masarati] Again the design of these queries need to be reworked
