Hi Marcel, I  was using an ldap browser looking for the 
GlueCEAccessControlBaseRule of the queue you are requiring and atlas is 
not present even if the ATLAS VOView (GlueVOViewLocalID) is  there, I 
honestly do not know if this can cause problems, the match making in the 
wms is done against the woview but maybe there is a previous check on 
the ACBR of the queue, but not sure about that.
Do you belong to any of these VOs: dech, dgtest,ghep,hp?  just to try 
and i search of an hint.
Cheers,
   Daniele.
