我有一个情况。使用Python，我创建了一个进程（以SYSTEM或Administrator用户身份运行），我需要使用不带密码的其他用户名来调用应用程序。所以阅读这个链接，结论是可能的，模仿另一个没有密码的用户，使用Kerberos ...但我没有找到任何用Python编写的解决方案，实际上我不知道是否有更好的方法解决这个问题
https://blogs.msdn.microsoft.com/winsdk/2015/08/28/logon-as-a-user-without-a-password/
Python 3.4.1 x64，Windows 7。
任何人都可以帮助我吗？
非常感谢！

这是ctypes包装器的粗略草稿，用于调用LsaLogonUser进行MsV1交互式登录，MsV1 S4U登录（用户，批处理服务）或Kerberos S4U域登录。
