Tomas--

Thanks--it certainly seems close, you're right! It looks, however like an
OIDC provider still uses a static configuration even though it loads it
from the discovery URL--that is, once it's loaded at configuraiton time, it
doesn't discover new changes, and there isn't an option to refresh/store
that discovery endpoint outside of configuration.

It's not clear to me how important that feature is--on one hand, it seems
unlikely that we should expect frequent changes; on the other, in the short
time since I started exploring this setup, I have encountered three changes
in google's OIDC endpoints between what was hard-coded into keycloak, what
is in their documentation, and what their current discovery endpoint
provides. (And, the google docs specifically suggest refreshing from the
endpoint periodically).

Thoughts?

James
