I am running a Kubernetes Cluster with an Nginx-ingress fronting couple of web apps. Because Nginx doesn't support SSO/OIDC by default, I use an oauth_proxy for authentication.

Everything is working, only verified users are able to access the web pages.

Is it possible to pass or request information from the Identity Provider to the client?

Edit

I already use oauth2_proxy (https://github.com/pusher/oauth2_proxy) with Azure AD. The issue is that I need all user details from the IP.

Logs from my oauth2_proxy:
