While debugging I have found that the token is extracted from the session OK in openstack_auth/backend.py(48) however it does not have an attribute 'user' as it does when authenticating against the original node (01).  The token pulled from the session does however have a 'user' with a more comprehensive structure in it than is expected if the 'user' attribute exists.

Are you running openstack_auth from master? Or was that just for debugging? The ubuntu cloud archive ships with 1.0.7, it's possible more recent releases introduced a compatibility issue.
