[Users] oVirt and IPA

Hi, I found an issue with IPA (and DNS) and oVirt. If I have hosted IPA server in ovirt and have enabled login thru IPA to oVirt and I stop IPA VM, I can not do anything in oVirt. I can not even log in to oVirt, because login dialog is grayed out (I think it waits on reaching IPA server). Of course I use IPA as primary DNS server for oVirt. After some time oVirt lets me input local admin credentials and waits on something. I have more ipa servers, so I think login authentication should fall back to another IPA server, but it does not.
