Как создать функциональность RUNAS/NETONLY в программе (С#/. NET/WinForms)?

Я собрал эти полезные ссылки:

Оказывается, мне придется использовать LOGON_NETCREDENTIALS_ONLY с CreateProcessWithLogonW. Я посмотрю, могу ли я обнаружить программу, если она была запущена таким образом, а если нет, соберите учетные данные и запустите сам. Таким образом, будет только один автономный EXE.

Я знаю, что это старый поток, но это было очень полезно. У меня такая же ситуация, как у Cade Roux, так как я хотел/нестандартного стиля.

Ответ Джона Раша работает с одной небольшой модификацией.

Добавьте следующую константу (вокруг строки 102 для согласованности):

private const int LOGON32_LOGON_NEW_CREDENTIALS = 9;

Затем измените вызов на LogonUser, чтобы использовать LOGON32_LOGON_NEW_CREDENTIALS вместо LOGON32_LOGON_INTERACTIVE.

Это единственное изменение, которое я должен был сделать, чтобы заставить это работать отлично!!! Спасибо, Джон и Кейд!

Ответ 3

Я просто сделал что-то похожее, используя ImpersonationContext. Он очень интуитивно понятен и отлично работает для меня.

Для запуска в качестве другого пользователя синтаксис:

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

Вот класс:

Этот код является частью класса RunAs, который мы используем для запуска внешнего процесса с повышенными привилегиями. Передача null для имени пользователя и пароля будет запрашиваться со стандартными предупреждениями UAC. При передаче значения для имени пользователя и пароля вы можете фактически запустить приложение без приглашения UAC.

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 );

Я полагаю, вы не можете просто добавить пользователя для приложения к серверу sql, а затем использовать аутентификацию sql, а не проверку подлинности Windows?
