C# 模拟和目录条目

我正在成功模拟用户帐户，但我无法使用模拟帐户绑定到AD并下拉

DirectoryEntry

以下代码输出：

• 在模拟之前，我是：域\用户
• 模拟后我是：域\管理员
• 错误：C:\Users\user\ADSI\u模拟\bin\Debug\ADSI\u模拟.exe samaccountname：

我的问题似乎类似于：

我正在获得一个主要代币。我知道我需要使用委派在远程计算机上使用模拟令牌。我确认该帐户没有选中“帐户敏感且无法委派”的标志。我还确认本地组策略和域组策略不会阻止委派：

计算机配置\ Windows设置\安全设置\本地策略\用户权限分配\

我错过了什么

谢谢

许多.NETAPI没有考虑您的手动模拟，例如您注意到的LDAP查询。因此，您需要使用DirectoryEntry的重载构造函数

错误（0x80004005）：未指定的错误

我在连接到远程windows时遇到了一些问题，通过了身份验证，出现了错误（0x80004005）：未指定的错误。我决定如下：

//Define path
//This path uses the full path of user authentication
String path = string.Format("WinNT://{0}/{1},user", server_address, username);
DirectoryEntry deBase = null;
try
{
    //Try to connect with secure connection
    deBase = new DirectoryEntry(path, username, _passwd, AuthenticationTypes.Secure);

    //Connection test
    //After test define the deBase with the parent of user (root container)
    object nativeObject = deBase.NativeObject;
    deBase = deBase.Parent;

}
catch (Exception ex)
{
    //If an error occurred try without Secure Connection
    try
    {
        deBase = new DirectoryEntry(path, username, _passwd);

        //Connection test
        //After test define the deBase with the parent of user (root container)
        object nativeObject = deBase.NativeObject;
        deBase = deBase.Parent;
        nativeObject = deBase.NativeObject;

    }
    catch (Exception ex2)
    {
        //If an error occurred throw the error
        throw ex2;
    }
}

希望有帮助。 小海尔维奥

感谢您确认这是唯一的方法。我想既然我将拥有用户的用户名/密码，那么没有理由不起作用。@Lex Li我问了一个相关的问题，请检查一下：
