how have you thought to supply the password, if user already logged into AD?
this is dup of bug#1113937
this also can be done in 3.5 by enforcing basic authentication, and access https://user:password@xxx/ovirt-engine/userportal, but this is unrecommended, and requires knowledge of user's password anyway.
