Python中的NTLM身份验证
Python中的NTLM身份验证
提问于 2010-06-04 04:21:46
我正在尝试使用python从Windows 7在IIS (Windows Server 2003)上实现NTLM身份验证。LAN Manager身份验证级别:仅发送NTLM响应。
客户端计算机和服务器在同一个域中。
域控制器(AD)在另一台服务器(也运行Windows server 2003)上。
我收到401.1 -未授权:由于凭据无效，访问被拒绝。您能否帮助我找出此代码的问题所在，并/或向我展示解决此问题的其他可能方法(使用NTLM或Kerberos)？

res_file.write(res)
res_file.close()谢谢!

我已经找出出了什么问题。我应该让连接保持活跃。这就是好东西！现在这个问题解决了。
