[Users] Adding users

Hi, I just installed oVirt and so far things seem to be running smoothly for the 1-node setup. I can't seem to add users though. When I go to Users->add I only get a search dialog that lists the admin user no matter what I enter as search string and there seems to be no obvious way to actually add a new user. Clicking "ok" just dismisses the dialog. Also after installing my first VM, stopping it and starting it up again the console icon stayed greyed out. I actually had to restart my browser and log back in in order to make the console icon clickable again. Regards, Dennis
