Subject Re: Extending StandardOidcIdentityProvider
Date Tue, 19 Jan 2021 14:44:02 GMT

1) I don't think NiFi currently supports the client id + x509
scenario, is this part of the OIDC standard? If so then maybe it can
be an improvement that is implemented.

2) The OIDC code in NiFi is not part of an extension point, so you
can't just plug in your own version. You would have to modify the code
in NiFi and rebuild the nifi-framework-nar with your changes.
