Use NGINX to proxy a website that uses windows authentication

Hi,

I'm well aware of the security implications of the thing that I'm trying to do but I would like to accomplish this just for testing purposes. Is it possible (for testing environment only of course) to set NGINX as a reverse proxy to a website that uses Integrated Windows Authentication but set NGINX not to require authentication at all (or at least use basic authentication only) and instead use credentials that will be specified in the NGINX config files?

Tnx.
