Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Some OIDC servers ignore "Accept: application/json" when requesting a flow that they don't support. Consequence: Such OIDC servers may respond with an HTML page that the authentication operator fails to parse as it's expecting json. The authentication operator failed to honor the IdP config in that case. Fix: Have the authentication operator ignore the error and don't allow CLI-logins for such OIDC servers. Result: The IdP config for all properly-working OIDC servers should now be functioning.
