Also look into Wine. Kai did something very similar there a long time
Your task is fairly easy as the resulting HTTP session won't be NTLMSSP
encrypted, just authenticated with NTLMSSP, so you don't need to
involve Samba long-term, or get out encryption keys.
See the 'squid' helper modes, there is ntlmssp-client-1 that you should
You can also play with NTLMSSP over mouse-buffer between that and the
squid-2.5-ntlmssp server mode. Set --password on the server and it
becomes standalone binary that does not need Samba running.
I hope this helps,
