Hi Michael, It is possible to use Keycloak as an identity provider and federate over SAML 2.0 or OpenID Connect. Please see this documentation for more details https://docs.openstack.org/keystone/latest/admin/federation/configure_federa... There are a few improvements in later versions with regards to federation, so I would advise upgrading if possible. Most importantly, Mitaka has been End Of Life, and hence unsupported since 2017-04-10. But outside of that, you’re good to go.

Hi, we have an OpenStack Mitaka installation running (yes I know it's pretty old ;-) ) at our lab and would like to use the keycloak-server from the central IT for authentication. So I would like to know if it is already possible in mitaka to use this external keycloak server or if this only possible in a later OpenStack version? Maybe anyone know and if yes is there any documentation how to do it? Was searching for it but found not much about it by now... Thanks :) Kind regards Michael Michael Stang Laboringenieur, Dipl.
