Summary

Currently, the Django-Nova/Dashboard supports only basic username/password based access. There is separate user credential management both on the web service point and OpenStack. OpenStack relies on the web server for user authentication resulting in Multiple Policy Decision Points (PDP). Integration of OpenID with Openstack allows flexible SSO mechanism for administrators. The solution also removes the existing multiple identity silos in web server and OpenStack.
