Keystone
What is Keystone?
Keystone is the identity service used by OpenStack for authentication (authN) and high-level authorization (authZ). It currently supports token-based authN and user-service authorization. It is scalable to include oAuth, SAML and openID in future versions. Out of the box, Keystone uses a SQLite DB as an identity store with the option to connect to external LDAP.

- The Service (ie: nova) shouldn't really care about the Role of the user. But we should be able to go back to the Auth-Z service to say "Can <token> [execute verb] on <some resource>" and get back a True/False from keystone. Nova itself, for example, shouldn't have to remember what capabilities a role has. But this may be cached.
