sample-angular-oauth2-oidc-with-auth-guards | Basic example of how to integrate the angular-oauth2-oidc | Authentication library

In my project i have an angular app where i use https://github.com/manfredsteyer/angular-oauth2-oidc and a SpringBoot backend. In the UI i copied most of the Stuff from here https://github.com/jeroenheijmans/sample-angular-oauth2-oidc-with-auth-guards.

My Code works with https://demo.identityserver.io and with a local Keycloak.

I only have to change the only:

• spring.security.oauth2.resourceserver.jwt.jwk-set-uri (in the Backend)
• In the frontend "issuer: 'http://localhost:8080/realms/master'," to fit to the corresponding server

My "Dream" would be to use the spring-authorization-server. In my app i can create User dynamicly, and there for i need to be able to add this user to the authorization-server with a REST call. As fare as i understand, the spring-authorization-server code that should be ease to extend.

I copied over the spring-authorization-server code from https://www.baeldung.com/spring-security-oauth-auth-server with the base spring-authorization-server version: 0.2.0. The Server starts and my App does the Redirect to the LoginPage. When it comes back from the spring-authorization-server the angular UI OIDC code detect a problem with the "Nonce", sometimes is missing, sometimes it does not match. Unfortunately i was not able to find the reason for that behaviour :-( As my code works with the other two implementations, i suspect either a misconfiguration or a bug in the spring-authorization-server.

The documentation on spring-authorization-server is pretty slim.

Question: Does somebody know a place where a spring-authorization-server is used with a web client an OpenId Connect?

2.3.2022 Update: I open a Issue at the spring-authorization-server https://github.com/spring-projects/spring-authorization-server/issues/640 I hope this will bring some more info.
