This is the identity service used by OpenStack for authentication (authN)
and high-level authorization (authZ). It currently supports token-based
authN with user/service authZ, and is scalable to support OAuth, SAML,
and OpenID in future versions. Out of the box, Keystone uses SQLite for
its identity store database, with the option to connect to external LDAP.
