如何将 RUNAS /NETONLY 功能构建到 (C#/.NET/WinForms) 程序中？

Question

我们的工作站不是 SQL Server 所在域的成员。 （它们实际上根本不在域中 - 不要问）。

当我们使用 SSMS 或任何其他方式连接到 SQL Server 时，我们将 RUNAS /NETONLY 与 DOMAIN\user 一起使用。 然后我们输入密码并启动程序。 （RUNAS /NETONLY 不允许您在批处理文件中包含密码）。

因此，我有一个需要 SQL 连接的 .NET WinForms 应用程序，用户必须通过运行具有 RUNAS /NETONLY 命令行的批处理文件来启动它，然后启动 EXE。

如果用户不小心直接启动EXE，则无法连接到SQL Server。

右键单击该应用程序并使用“运行方式...”选项不起作用（可能是因为工作站并不真正了解该域）。

我正在寻找一种方法，让应用程序在启动任何重要操作之前在内部执行 RUNAS /NETONLY 功能。

请参阅此链接以了解 RUNAS /NETONLY 如何工作的说明： http:// /www.eggheadcafe.com/conversation.aspx?messageid=32443204&threadid=32442982

我想我必须将 LOGON_NETCREDENTIALS_ONLY 与 CreateProcessWithLogonW 一起使用>

Answer 1

我知道这是一个旧线程，但它非常有用。 我的情况与 Cade Roux 完全相同，因为我想要 /netonly 风格的功能。

John Rasch 的答案只需稍作修改即可！！！

添加以下常量（在第 102 行左右以保持一致性）：

private const int LOGON32_LOGON_NEW_CREDENTIALS = 9;

然后将对 LogonUser 的调用更改为使用 LOGON32_LOGON_NEW_CREDENTIALS< /code> 而不是 LOGON32_LOGON_INTERACTIVE。

这是我必须做出的唯一更改才能使其完美运行！ 谢谢约翰和凯德！

Answer 2

我刚刚使用 ImpersonationContext 做了类似的事情。 它使用起来非常直观，并且非常适合我。

要以不同用户身份运行，语法为：

using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) )
{
    // code that executes under the new context...
}

这是类：

namespace Tools
{
    #region Using directives.
    // ----------------------------------------------------------------------

    using System;
    using System.Security.Principal;
    using System.Runtime.InteropServices;

事实证明，我将不得不将 LOGON_NETCREDENTIALS_ONLY 与 CreateProcessWithLogonW 一起使用。 我将看看是否可以让程序检测它是否已以这种方式启动，如果没有，则收集域凭据并自行启动。 这样就只有一个自我管理的 EXE。

Answer 4

使用此处非常有用的答案，我创建了下面的简化类，该类使用 .NET Standard 中也提供的 API：

public class Impersonator
{
    [DllImport("ADVAPI32.DLL", SetLastError = true, CharSet = CharSet.Unicode)]
    private static extern bool LogonUser(
        string lpszUsername,
        string lpszDomain,
        string lpszPassword,
        int dwLogonType,
        int dwLogonProvider,
        out SafeAccessTokenHandle phToken);

    public void RunAs(string domain, string username, string password, Action action)
    {
        using (var accessToken = GetUserAccessToken(domain, username, password))
        {
            WindowsIdentity.RunImpersonated(accessToken, action);
        }
    }

    private SafeAccessTokenHandle GetUserAccessToken(string domain, string username, string password)
    {
        const int LOGON32_PROVIDER_DEFAULT = 0;
        const int LOGON32_LOGON_NETONLY = 9;

        bool isLogonSuccessful = LogonUser(username, domain, password, LOGON32_LOGON_NETONLY, LOGON32_PROVIDER_DEFAULT, out var safeAccessTokenHandle);
        if (!isLogonSuccessful)
        {
            throw new Win32Exception(Marshal.GetLastWin32Error());
        }

        return safeAccessTokenHandle;
    }
}

以下是使用它的方法：

_impersonator.RunAs(
    "DOMAIN",
    "Username",
    "Password",
    () =>
    {
        Console.WriteLine("code executed here runs as the specified user with /netonly");
    });

Answer 5

此代码是 RunAs 类的一部分，我们用它来启动具有提升权限的外部进程。 为用户名和参数传递 null 密码将通过标准 UAC 警告提示。 当传递用户名和密码的值时，您实际上可以在没有 UAC 提示的情况下启动提升的应用程序。

public static Process Elevated( string process, string args, string username, string password, string workingDirectory )
{
    if( process == null || process.Length == 0 ) throw new ArgumentNullException( "process" );

    process = Path.GetFullPath( process );
    string domain = null;
    if( username != null )
        username = GetUsername( username, out domain );
    ProcessStartInfo info = new ProcessStartInfo();
    info.UseShellExecute = false;
    info.Arguments = args;
    info.WorkingDirectory = workingDirectory ?? Path.GetDirectoryName( process );
    info.FileName = process;
    info.Verb = "runas";
    info.UserName = username;
    info.Domain = domain;
    info.LoadUserProfile = true;
    if( password != null )
    {
        SecureString ss = new SecureString();
        foreach( char c in password )
            ss.AppendChar( c );
        info.Password = ss;
    }

    return Process.Start( info );
}

private static string GetUsername( string username, out string domain ) 
{
    SplitUserName( username, out username, out domain );

    if( domain == null && username.IndexOf( '@' ) < 0 )
        domain = Environment.GetEnvironmentVariable( "USERDOMAIN" );
    return username;
}

Answer 6

我想你不能只将应用程序的用户添加到 sql server，然后使用 sql 身份验证而不是 windows 身份验证？

Answer 7

对于 .NET Core，WindowsImpersonationContext 和 WindowsIdentity.Impersonate() 不可用。

以下是 .NET Core 类似解决方案的链接。 WindowsImpersonationContext 和 WindowsImpersonationContext 在 ASP.Core 中找不到 Impersonate()
