OAuth2 spring security - resource and authorization server same but different authentication server

问题

I have a case where my authentication server is different whereas authorizaion and resource servers are same. I have created one dummy application where it works fine with same authentication and authrorization server but not when they are different. I can navigate to authentication server from Spring security but not sure how to pass the value that it is authenticated.
