[Users] DNS for IPA in oVirt

Hi list, I don't want to ask my question in the mail thread of Eduardo to avoid mixing topics. Can you give me more detailed information on how oVirt is using DNS internally and how IPA users can work in the following scenario: # engine-manage-domains -action=list Domain: ovido.at User name: admin(a)OVIDO.AT Manage Domains completed successfully # cat /etc/hosts | grep engine 10.0.100.195 ovirt-engine.lab.ovido.at # ip a 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:1a:4a:00:64:14 brd ff:ff:ff:ff:ff:ff inet 10.0.100.195/24 brd 10.0.100.255 scope global eth0 # host ovirt-engine.lab.ovido.at ovirt-engine.lab.ovido.at has address 10.0.100.24 # host 10.0.100.24 24.100.0.10.in-addr.arpa domain name pointer ovirt-engine.lab.ovido.at. So in my case I have correct DNS settings (forward and reverse), but my ovirt-engine host has a totally different IP address. I didn't test SSO with Kerberos in user portal (maybe this want work), but authentication with IPA user in user portal and admin portal is working fine even with these totally wrong DNS configuration.
