Sorry I'm late in joining in on this thread - the dlist change screwed me up

Anyway - I've got NTLM working through the first part of the
Challenge/Response for NTLMv1 and NTLM v2, including v2's signing and
sealing (I believe).  What an amazing piece of work :-)

Most of what I'm working on has been taken from the LibCurl library, but my
C skills are sorely lacking, and there are some config items in LibCurl that
I'm not sure that we have in our ntlm.c.

I can forward what I've got to anyone, including the inline diags that I've
got.  Works gotten crazy (again) so haven't had time to work why my final
response calculation is failing.  NTLMv2 uses MD5 vs NTLMv1's MD4.

This obviously should be a priority for the next release - I'm currently
using two versions of Wget.exe for internal stuff :-)
