idp external auth via openid

[Kapetanakis Giannis]

Hi,

I'm trying to delegate idp's authentication to an external openid provider (Keycloak in this case) using openid.

Has anyone done this?

I've done a similar thing using CAS with shib-cas-authn.
Is there a similar approach for openid? Probably I can do it with CAS since there is a plugin for Keycloak, but I would prefer a more native way.

Thanks,

G
