@Experts,
We have nginx-ingress controller with Authentication added via <http://nginx.ingress.kubernetes.io/auth-type|nginx.ingress.kubernetes.io/auth-type>
Is it possible from application end to identify which user ID made the request ?

Malayamanas Panda:
User information should be captured in the NGINX access log that is used for Ingress controller deployment (multiple pods as replicaset). https://kubernetes.github.io/ingress-nginx/examples/auth/basic/
