Multi-factor authentication to RHEV-4.1

We have been asked to explore multi-factor authentication for the RHEV-User and Admin portal. We are currently using the ovirt-engine-extension-aaa-ldap-setup to connect into the authentication servers.

Has anyone had any luck configuring ovirt-engine-extension-aaa-ldap for multi-factor authentication with RHV?

If not, has anyone had any luck creating a RADIUS authentication for RHV?

Thanx

Frank
