我成功模拟了一个用户帐户,但无法使用模拟的帐户绑定到 AD 并拉取
以下代码输出:
谢谢!
DirectoryEntry
。以下代码输出:
- 模拟之前我的身份是:DOMAIN\user
- 模拟之后我的身份是:DOMAIN\admin
- 错误:C:\Users\user\ADSI_Impersonation\bin\Debug\ADSI_Impersonation.exe samaccountname:
如何在 ASP.NET 中使用 System.DirectoryServices 命名空间
我正在获取一个主要令牌。我了解需要使用委派来在远程计算机上使用模拟令牌。我确认该帐户未选中“帐户是敏感的,不能委派”标志。我还确认本地组策略和域组策略未阻止委派:计算机配置\Windows 设置\安全设置\本地策略\用户权限分配\
我漏掉了什么?谢谢!
