So, if I understand it correctly, it is then possible that a service user for Nova can actually accidentally nuke an endpoint for a Glance service, for example?  Don't we want isolation among services, i.e., a user owning one service may not modify another service that he/she did not create?

Hi Liem!

As Joe Heck noted, the concept of roles hasn't changed from the Diablo 
codebase, and there is certainly the danger of a service tenant user 
nuking an endpoint for a different service, as you describe above. In 
Glance, we added a config option "admin_role" that can be set to guard 
against this, however. Just set admin_role = glance_admin and create a 
glance_admin role in Keystone and just assign the Glance service user 
(and only that user) that role...

Kind of a hacky workaround, but it works...

Best,
