keystoneauth-oidc 1.0.0

OpenID Connect support for OpenStack keystoneauth library

OpenID Connect support for OpenStack clients

This is a set of authentication plugins for the OpenStack clients (namely for the keystoneauth1 library) which provides client support for authentication against an OpenStack Keystone server configured to support OpenID Connect using the Keystone Open ID Connect plugin or the Apache's mod_auth_openidc, as described below.

Available plugins

v3oidc plugin

This plugin allows you to authenticate with a Keystone server configured to use the Keystone Open ID Connect plugin. It will perform out-of-bound authentication with the sever, meaning that the only OpenID Connect client (Relying Party) is the Keystone Server.

No OpenID Connect credentials are required in this case.

v3oidccode plugin (old method)

This plugin allows to authenticate against Keystone using the Authorization Code grant type of OpenID Connect and OAuth 2.0, using the OpenStack client as an OpenID Connect Relying Party. This plugin is compatible with Keystone configured with the Apache HTTP server and the mod_auth_openidc and the Keystone Open ID Connect plugin.

This plugin requires that you configure an OpenID Connect client in your OpenID Connect Provider and pass the client credentials to the plugin. The OpenStack CLI will handle the authentication with the OpenID Connect Provider, obtaining and access token, that will be exchanged with the Keystone server in order to obtain a Keystone token.

v3oidccode plugin (old method)

First of all, you need to create an OpenID Connect client in your OpenID Connect Provider. Then, you have to specify the v3oidccode in the --os-auth-type option and provide a valid autorization endpoint with --os-authorization-endpoint or a valid discovery endpoint with --os-discovery-endpoint. The <identity-provider> and <protocol> must be provided by the OpenStack cloud provider.
