[ovirt-users] Problem with adding more users - engine-manage-domains is missing

Hello, I am not really sure this is the right way to contact oVirt support or anything like that, but I would like to ask about something I have a problem with. I have my oVirt server up and running, virtualiaztion works fine, console is wokring and everything so the next logical step would be adding more users, because I am still stuck with admin user and nothing else. I've done my research and discovered you need to use engin-manage-domains to add extra domain which would host users for you and then you just load them in your oVirt enviroment and assign roles to them. However, on my server, nothing like engine-manage-domains exists, it only shows "command not found". I googled and found out that this service is automaticly isntalled when you install oVirt engine, but nothing like that happened on my server. I tried to reinstall, but the service is still missing. When installing, there are no fails or missing repositories. What are my options? Also, do I need another server for the storage of users or can it be running on the same IP as host and oVirt? Thank you very much i advance, Regards, Martin Kozl
