Hi Thomas,     Thanks for the quick reply . Here is the scenario that I am looking for. Once the user gets authenticated, is there a way to pass some attributes of the user (say for example, company, emailid, status of the user etc...) as a part of the response headers?  Regards,Subrahmanyam.

Based on that I think that mod_auth_oidc might do what you want. https://github.com/keycloak/securing_apps_guide/blob/master/topics/oidc/m... https://github.com/thomasdarimont/keycloak_mod_auth_oidc_example/blob/mas...

Please let me know on this.
