来自 TFS 错误的 Git 克隆：RPC 失败；结果 = 22，HTTP 代码 = 401

Question

我目前正在尝试在我的 Mac 上从 TFS 克隆存储库，但出现以下错误：

$ git clone https://tfs.xx.com/yy/_git/Mobile
Cloning into 'Mobile'...
Username for 'https://tfs.xx.com': xxx
Password for 'https://xxx@tfs.xx.com': 
error: RPC failed; result=22, HTTP code = 401
fatal: The remote end hung up unexpectedly

环境：

• Mac OS X EI Captian 版本 10.11.1
• Git 2.3.8 (Apple Git-58)
• TFS 2015

谷歌搜索了几种可能的解决方案，但都失败了。

1. 增加 http post 缓冲区

   git config --global http.postBuffer 524288000

2. 在安全钥匙串中缓存凭据

   git config --global credential.helper osxkeychain

3. 升级git到最新版本v2.6.4（失败后卸载）

我怀疑根本情况可能是 TFS 服务器上的身份验证配置。不基于窗口 NTLM 的 TFS 服务器阻止访问。这么说，我的证据是当我使用 GIT_CURL_VERBOSE=1 运行 git 时。它在日志末尾显示了更多详细信息。有消息：

* NTLM handshake rejected
* Authentication problem. Ignoring this.

好吧，当我在 Windows 上调用相同的命令时。它执行正确。不同的是windows显示的是：

* NTLM auth restarted

然后继续。 Mac 回应时：

* NTLM handshake rejected
* Authentication problem. Ignoring this

然后停止。

有时会因为网速慢而出现此问题。请尝试以更好的网络速度克隆存储库。
