OIDC/OAuth2 token introspection in Keystone


There is an patch to improve the documentation for using the CLI with OIDC, but it hasn't merged yet. See here https://review.opendev.org/#/c/693838

Keystoneauth has plugins in place for authenticating with the OIDC IdP in multiple ways, including using an access token, see here https://github.com/openstack/keystoneauth/blob/master/keystoneauth1/identity/v3/oidc.py

Best,
Kristi

Many thanks Nikolla,

I was able to federate using OIDC IdP via the dashboard. I meant the problem is authenticating via CLI providing a OIDC token via command line, but maybe you already answered to my request.


BR,

Michele

Hi Michele,

We just approved a feature request for that [0], however it was merged to backlog, meaning no specific timeline for it being implemented yet.

With the current implementation, you can use OAuth 2.0 Access Tokens with Keystone, however the token introspection endpoint will be used, therefore only the claims contained in the access token will be returned. I am assuming your question is with regards to the userinfo endpoint and OIDC claims, which we do not currently support.

Hi all, my question is:

could OS Keystone support OIDC/OAuth2 token introspection/validation. I mean for example executing a swift command via CLI adding a OIDC token bearer as a parameter to the swift command. In this case Keystone should validate the OIDC token towards and external IdP (using introspection endpoint/protocol for oidc).

Is this currently supported, or eventually would be done in the near future?

thanks Michele
