I would expect that the API of each service would have to interpret the role assigned to a user in the context of that service - roles for swift nova glance quantum etc would probably carry very different semantics.
So, to my understanding, key stone provides authentication and user information - what tenants the user has access to, and what roles the user is assigned. The mapping of these to what the user can do on what instances in each service are left for the service to determine.
