Comment 4 for bug 1418341

So, correct ones according to http://docs.openstack.org/developer/keystonemiddleware/middlewarearchitecture.html and https://github.com/openstack/keystonemiddleware/blob/b562b04ee5db309268716e0e1b8270f30bdf1a76/keystonemiddleware/auth_token.py#L645-L661 are ones with admin_ prefix. I have no idea, why in devstack it is different: https://github.com/openstack-dev/devstack/blob/9b215db569dcee2e9cd52c3336ba14b73ad05ab0/lib/keystone#L447-L449 but it might devstack problem. Ironic seems to follow the official documentation.
