The NTLM authentication method was designed by 21Microsoft and is used by IIS web servers. It is a proprietary protocol, 22reverse-engineered by clever people and implemented in curl based on their 23efforts. This kind of behavior should not be endorsed, you should encourage 24everyone who uses NTLM to switch to a public and documented authentication 25method instead, such as Digest. 26 27If you want to enable NTLM for your proxy authentication, then use 28--proxy-ntlm. 29
