我在共享Windows服务器上有一个用户的SID字符串(例如,"S-1-5-21-500000003-1000000000-1000000003-1001"),我需要获取相关的用户名.
I have a SID string (e.g., "S-1-5-21-500000003-1000000000-1000000003-1001") of a user on a shared Windows server, and I need to get the related username.
我想这可以通过以下方式实现:1)将SID字符串转换为字节数组.2)使用适当的ldpa查询来获取相关的用户名.
I suppose that this may be achieved by: 1) Turning the SID string into byte array. 2) Using a suitable ldpa query to get the related username.
但是我没找到准确可靠的方法说明(以这种方式或其他方式).
But I failed to find exact and reliable instructions of how to do it (this way or another).
我会感激任何有用的指南,特别是如果它带有演示Python(ldap3)代码.
I'll appreciate any useful guide, especially if it comes with demo Python (ldap3) code.
谢谢!
