Cool.

Or Apache modules like mod-auth-openidc (OIDC) or mod-auth-mellon
(SAML).

Keycloak, as a broker, is similar. Service provider can be using one
protocol and the identity provider another.

Gitlab can use OIDC for OmniAuth, so it can authenticate against any
OIDC-compliant IdP, LLNG and Keycloak included.

Redhat has the distinction (thankfully) of not following a 'freemium'
model (at least for Directory389 and Keycloak). The features available
in RedHat SSO and Keycloak are identical. Redhat SSO lags behind
Keycloak but may include fixes not yet ported to Keycloak. Keycloak is
also totally free and, yes, is written in Java.

Please work with Michael Lustfield (IRC MTecknology) as he is also
interested in setting upa Debian-specific instance of LLNG.

More thought required but don't disagree.

Agree and/or mod-auth-openidc/mod-auth-lemon, etc.

Agree but with order of preference being OIDC, SAML and... way over
there, almost too distant to see... CAS.

Very helpful response!
