Authentication is half-broken

[Dmitry Tantsur]

Testing showed that our authentication is not working properly. It does allow in a mere user, but it prevents Ironic user from accessing the API. http://lists.openstack.org/pipermail/openstack-dev/2015-February/057980.html contains proposed improvements.

Despite introducing a new dependency, needs backport to stable/1.0.
