I suspect that it will become clearer where the problem might be, if
you can show one request that you make that works when you avoid nginx;
and show the same request through nginx and show the corresponding
failure response.

If you can use "curl -v" to send the request, with whatever user/pass
credentials you use obviously marked, then it may help to copy-paste
the request and response.

If you are using http basic authentication on IIS, then it should Just
Work. If you are using ntlm authentication on IIS, then it will not work
through any proxy or reverse proxy (unless it has specific ntlm support).

Good luck with it,
