Does git clone work through NTLM proxies?

Question

I've tried both using export http_proxy=http://[username]:[pwd]@[proxy] and git config --global http.proxy http://[username]:[pwd]@[proxy].

I couldn't make it work. It looks like git uses Basic authentication:

Initialized empty Git repository in /home/.../.git/ * Couldn't find host github.com in the .netrc file, using defaults * About to connect() to github.com port 8080 (#0) *   Trying 10.... * Connected to github.com (10....) port 8080 (#0) * Proxy auth using Basic with user '...' > GET http://github.com/sunlightlabs/fiftystates.git/info/refs HTTP/1.1 Proxy-Authorization: Basic MD... User-Agent: git/1.6.1.2 Host: github.com Pragma: no-cache Accept: */* Proxy-Connection: Keep-Alive  < HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to t he Web Proxy filter is denied.  ) < Via: 1.1 ... < Proxy-Authenticate: Negotiate < Proxy-Authenticate: Kerberos < Proxy-Authenticate: NTLM < Connection: Keep-Alive < Proxy-Connection: Keep-Alive < Pragma: no-cache < Cache-Control: no-cache < Content-Type: text/html < Content-Length: 4118 * The requested URL returned error: 407 * Closing connection #0 fatal: http://github.com/sunlightlabs/fiftystates.git/info/refs download error - The requested URL returned error: 407 

Google search returned mixed and probably not updated results. Somewhere it says that curl is (was?) used under the hood, but its options are (were?) hardwired into code. For example,

curl --proxy-ntlm --proxy ...:8080 google.com 

works, and I'd like to use the same option with git.

I need some more definite answers here: has anybody succeed using git through Windows proxies? Which version?

Thanks.

Default NTLM credentials

In order to use default NTLM credentials, provide an empty username and password

git config --global http.proxy https://:@proxy:port 

Firewall Client for ISA Server

Instead of setting proxy for git, npm, etc. you can use Firewall Client for ISA Server from Microsoft. After installation:

Start > Autostart > Microsoft Firewall Client Management

Settings tab > Manual specified ISA Server > proxy:port Web Browser tab > Uncheck "Enable web browser automatic configuration."
