Comment 1 for bug 2065590

I replicated the behavior you described in your bug report on a minimal install of Keystone + OpenStack Dashboard on Yoga/stable with the keystone-openidc charm on latest/edge like you described. I also get redirected to the same kind of URL - http://10.20.0.83:5000/v3/auth/OS-FEDERATION/identity_providers/keycloak/protocols/openid/websso?origin=http://10.20.0.84/horizon/auth/websso/.

That is the URL that is rendered into the Apache configuration at /etc/apache2/openidc/openidc-location.openid.conf on the Keystone unit in my installation.

I'm not familiar enough with the Keystone OpenIDC integration to say what exactly is happening at this time, but I will continue to look into what is causing the behavior we are seeing. I will report back when I have more information.
