[Users] Free IPA + oVirt setup fails

[i iordanov]

Hey,

I actually realized that something I wrote is inaccurate.

UserB, who was not granted permission to any VM was actually able to
connect to a freshly booted UserA's VM. Subsequently, UserA was unable to
connect to "his own VM" anymore, and the error message was:

Operation Failed: [user cannot force reconnect to vm]

When UserB then shut down UserA's VM, UserA was able to power it on and
attach to it. Subsequently, UserB was not able to connect to the VM again
with the same message UserA was getting (user cannot force connect to vm).

What I expected is that UserB would not see, not be able to power control,
and not be able to attach at all to UserA's VM, so this behavior is quite
puzzling to me!

Any clarification and help would be appreciated!

Thanks,
iordan
