[ovirt-users] oVirt 4.3.1 with AD creates new user at every login

I just did a clean install of oVirt 4.3.1 (engine and nodes). I setup AD authentication and gave an AD group permissions needed work with VMs. I gave them PowerUserRole on the Cluster and Storage. Users in the AD group can login and create VMs but after they log out and log back in they don't see any of the VMs created in the previous session. I noticed that in Administration -> Users a new row is created for each user every time they login. All columns for each user are the same: same first and last name, same user name, authorization provider, and so on but the behavior looks very much like they are being treated as new user every time they login. Any idea what may be causing this? Thanks, -- Peter
