To me it looks like git changed the way it makes a curl call.
I think I've found the problem, and you're right -- Git has changed the way it makes the curl call. The culprit is commit 5841520b in the upstream Git repository, which has the following commit message: | http: always use any proxy auth method available | | We set CURLOPT_PROXYAUTH to use the most secure authentication | method available only when the user has set configuration variables | to specify a proxy. However, libcurl also supports specifying a | proxy through environment variables. In that case libcurl defaults | to only using the Basic proxy authentication method, because we do | not use CURLOPT_PROXYAUTH. | | Set CURLOPT_PROXYAUTH to always use the most secure authentication | method available, even when there is no git configuration telling us | to use a proxy. This allows the user to use environment variables to | configure a proxy that requires an authentication method different | from Basic. I can't confirm this is the problem, though, as I don't have a test environment that uses NTLM. Do you have the ability to either run a test version of Git I can produce that patches out this change, or (better) to build Git yourself without this patch to see if that is indeed the change that's causing the problem?
