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.

>- Fine-grained access control
- Non-admin users
- Create your own roles

- Stability
- Performance
- Deployability
- Documentation
- Enhancements
- Multiple-stack/Global use case (more than one nova deploy)
- Region/location
- Domains (https://blueprints.launchpad.net/keystone/+spec/keystone-domains)
- Federation
- First: integration with LDAP/AD
- Stretch: OpenID, SAML
- Also:
- Discovery/Registry(DNS and 35357)
- Metadata/tags

Releases
- Diablo
- Core functionality (calls shared by all implementations)
- Extensions(calls that are specific to the implementation; ie: enabling company "ACME" user, role, and group structure)
- Essex (Keystone is part of OpenStack core for Essex)
- Call for blueprints (feature freeze by start of e-2; code freeze by start of e-4: http://wiki.openstack.org/EssexReleaseSchedule)
- Scopes
- SCIM protocol (blueprint)
- Service endpoint location (https://blueprints.launchpad.net/keystone/+spec/service-endpoint-location)
- Federated Auth-Z requirements for Zones - FederatedAuthZwithZones
- 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.
- Identifying full-path URI for Keystone-Token (Keystone-Essex-Federated-Token)
- SQL schema migrations (ie - sqlalchemy-migrate migrations).
- Folsom
- Summit Topics
- Call for blueprints
