Our product needs to do NTLM proxy authentication directly. Does Mac
OS X expose any NTLM proxy authentication API that we can utilize? I
see a few frameworks and libraries that have private API for this, aka
non-exposed in headers that I have found.

On Windows we utilize Win32 SSPI library to do NTLM proxy
authentication directly.

We know that CFHTTP supports NTLM authentication (among other schemes)
however we cannot utilize CFHTTP since our product has the option/need
to tunnel via HTTPS proxies (we don't communicate using HTTP but with
our own protocol).

We could in theory utilize CFHTTP if we could use it to do the
authentication with the proxy (get things established) and then get
access to the socket that CFHTTP uses so we could send our own data.

Our product uses BSD sockets for its network communication currently.
