What configuration do you use in domain mode?
If you use the provides servers and server-groups you must change the full or full-ha profile.
The default profile is not used in the domain configuration.
Check what <server> do you use, in which server-group it is and what profile is used by this server-group.
Blame on me :-(
it was the wrong profile...
now it works
but - in web console I still cannot see the naming subsystem (if started in domain mode, in standalone mode there's a menu entry)
