Depending on the versions of Windows and what you are trying to do, it
may be possible to use Kerberos via Nginx, rather than NTLM. It
requires some foo setting up Service Principal Names, but does work
properly via an HTTP proxy, and provides passthrough auth, which seems
to be what the desire here is.
