Open Stack

Hi,

The 'cloud_admin' policy file requires domain-scoped to work to work.

Horizon does not currently support domain scope token yet. So yes, it is a
gap in horizon at the moment.

There are on-going patches to address this in horizon:
- https://review.openstack.org/#/c/141153/
- https://review.openstack.org/#/c/148082/

Dan (esp) prepared a nicely written document on this should eventually work.
