I have noticed lately that the SSO in ovirt seems to be broken on the 
engine side.
The bug https://bugzilla.redhat.com/show_bug.cgi?id=922398 addresses 
this issue.
And it has been fixed here: http://gerrit.ovirt.org/#/c/13667/

The reason for this is that the engine expects a certain package name to 
be reported by the guest agent to enable the SSO functionality on the 
engine side. If this information is not send the engine 'thinks' that 
there's no SSO capability.

There'd be a way to enable the SSO capability by modifying the ovirt 
guest agent installation. e.g. you could install a fake rhev-agent 
package, however I personally would not recommend that.

The ovirt 3.3 engine release should resolve this issue.

No. This is just reporting the currently logged in user.
