We need to make it more clear the relationship between keystone and user/tenants.
When you authenticate against keystone, a service is sent a token with an associated User/Tenant. The current backend of keystone supports a specific tenant/user model, but as far as the rest of openstack (nova/glance/swift/...), it should not make any assumptions about 1-1, 1-many, many-many.

Service providers and enterprise clouds will probably either provide their own implementation which would backend to existing accounts / users.
