本文介绍了Windows使用Python无需密码即可作为用户登录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我这里有个情况.使用Python,我已经创建了一个进程(以SYSTEM或Administrator用户身份运行),并且需要使用其他没有密码的用户名来调用应用程序.所以阅读下面的链接,结论是可能的,使用Kerberos来模拟另一个没有密码的用户...但是我没有找到任何用Python编写的解决方案,实际上我不知道是否有解决此问题的更好方法

I have a situation here. Using Python, I have a process been created (running as SYSTEM or Administrator user) and I need to call an application using a different username without password. So reading this link bellow, the conclusion is that could be possible, Impersonating another user without password, using Kerberos... but I am not finding any solution written in Python and actually I have no idea if there is a better approach for this problem.

Python 3.4.1 x64,Windows 7.

Python 3.4.1 x64, Windows 7.

有人可以帮我吗?

非常感谢!

PS:此可以使用"win32"模块来实现,但是我没有任何运行此target_user的进程来捕获进程令牌.

推荐答案

下面是一个用于调用 LsaLogonUser 用于MsV1交互式登录,MsV1 S4U登录(用户,批处理服务)或Kerberos S4U域登录.

Here's a rough draft of a ctypes wrapper to call LsaLogonUser for an MsV1 interactive logon, MsV1 S4U logon (service for user, batch), or Kerberos S4U domain logon.
