Cntlm was and what this port might have gotten you:
"About Cntlm proxy
Cntlm (user-friendly wiki / technical manual) is an NTLM / NTLM Session
Response / NTLMv2 authenticating HTTP proxy intended to help you break
free from the chains of Microsoft proprietary world. You can use a free
OS and honor our noble idea, but you can't hide. Once you're behind
those cold steel bars of a corporate proxy server requiring NTLM
authentication, you're done with. The same even applies to 3rd party
Windows applications, which don't support NTLM natively.
Here comes Cntlm. It stands between your applications and the corporate
proxy, adding NTLM authentication on-the-fly. You can specify several
"parent" proxies and Cntlm will try one after another until one works.
All auth'd connections are cached and reused to achieve high
efficiency. Just point your apps proxy settings at Cntlm, fill in
cntlm.conf (cntlm.ini) and you're ready to do. This is useful on
Windows, but essential for non-Microsoft OS's.
Cntlm integrates TCP/IP port forwarding (HTTP tunneling), SOCKS5 proxy
mode, standalone proxy allowing you to browse intranet as well as
Internet and to access corporate web servers with NTLM protection.
There are many advanced features like NTLMv2 support, password
protection, password hashing, completely mutliplatform code (running on
just about every architecture and OS out there) and so much more. Cntlm
eats up so little resources it can be used on embedded platforms as
well - it's written in plain C without any external dependencies."
Cntlm will likely be interesting for those in Microsoft environments
that are (still?) using NTLM, and not environments implementing
LDAP/Kerberos or such.
