Fixed acl handling in lists.n -Acls were not checked correctl. If we had permissions to view only phones, we got all systems listed, due to the fact that get_psermission can not differentiate between object types. We have to do this manually, not just iterate through all possible combinations of acl-categrory M      /root/2.6/gosa-all/gosa/plugins/admin/groups/class_filterGroupLDAP.inc dn and check if there is a -r- in the result.
