Also be aware that you need to use that engine FQDN to access oVirt 4.0 ​This is one of the oVirt 4.0 features​, we have implemented OAUTH SSO for all engine parts: webadmin, userportal and restapi. If you are using CAS (althought it's officially supported by oVirt), that probably means you have configured cas authentication on Apache, passing authenticated username using aaa-misc as authn extension and aaa-ldap as authz extension (to get group memberships for authenticated user). If that's true then please take a look at https://bugzilla.redhat.com/show_bug.cgi?id=1342192 there are some changes on Apache configuration (the bug is for kerberos, but I suspect similar config is needed also for cas module in apache).
