This kind of behavior should not be endorsed, you should encourage 13 everyone who uses NTLM to switch to a public and documented authentication 14 method instead, such as Digest. 15 16 If you want to enable NTLM for your proxy authentication, then use 17 --proxy-ntlm. 18 19 If this option is used several times, only the first one is used. 20
