[ovirt-users] Redirect login requests to FQDN

After upgrading to ovirt-engine 4 some of our users are receiving a message as follows.

The client is not authorized to request an authorization. It's required to access the system using FQDN.

Is there a way to direct ovirt login requests to the server's FQDN using mod_rewrite? I placed these rules in /etc/httpd.d/01- redirect.conf and restarted httpd however requests are never actually redirected. RewriteCond %{HTTP_HOST} !^ovirt-engine\.example\.com$ [NC,OR] RewriteRule ^ovirt-engine/(.*) https://ovirt-engine.example.com/ovirt-engine/$1 [L,R]
