Обнаружение домена пользователя в аутентификации формы ASp.net

Question

клиент отправил запрос в базу веб-приложений Asp.net при аутентификации формы. Как я могу получить имя пользователя Active Directory, зарегистрированного на клиенте?

Клиент и веб-приложение находятся в одном домене.

Answer 1

в моем приложении интранета я использовать что-то вроде этого:

/// <summary> 
     /// Authenticate the user, with windows auth(and domain) 
     /// If that fails then authenticate with forms 
     /// If that fails...well, go to hell 
     /// </summary> 
     /// <param name="sender"></param> 
     /// <param name="e"></param> 
     protected void loginControl_Authenticate(object sender, AuthenticateEventArgs e) { 

      //First try the windows login (domain+username/password) 
      Logging.IntranetLogger.LogIntranetActionInfo(Logging.IntranetLogConst.Logging, Logging.IntranetLogConst.UserTryToLoggIn, loginControl.UserName); 

      string domainName = GetDomainName(loginControl.UserName); // Extract domain name 
      //form provide DomainUsername e.g Domainname\Username 
      string userName = GetUsername(loginControl.UserName); // Extract user name 
      //from provided DomainUsername e.g Domainname\Username 
      IntPtr token = IntPtr.Zero; 

      //userName, domainName and Password parameters are very obvious. 
      //dwLogonType (3rd parameter): 
      // I used LOGON32_LOGON_INTERACTIVE, This logon type is 
      // intended for users who will be interactively using the computer, 
      // such as a user being logged on by a terminal server, remote shell, 
      // or similar process. 
      // This logon type has the additional expense of caching 
      // logon information for disconnected operations. 
      // For more details about this parameter please see 
      // http://msdn.microsoft.com/en-us/library/aa378184(VS.85).aspx 
      //dwLogonProvider (4th parameter) : 
      // I used LOGON32_PROVIDER_DEFAUL, This provider use the standard 
      // logon provider for the system. 
      // The default security provider is negotiate, unless you pass 
      // NULL for the domain name and the user name is not in UPN format. 
      // In this case, the default provider is NTLM. For more details 
      // about this parameter please see 
      // http://msdn.microsoft.com/en-us/library/aa378184(VS.85).aspx 
      //phToken (5th parameter): 
      // A pointer to a handle variable that receives a handle to a 
      // token that represents the specified user. We can use this handler 
      // for impersonation purpose. 


      //authenticate with the inputed 
      bool windowsLoginResult = LogonUser(userName, domainName, loginControl.Password, 2, 0, ref token);} 



[DllImport("ADVAPI32.dll", EntryPoint = "LogonUserW", SetLastError = true, CharSet = CharSet.Auto)] 

public static extern bool LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); 

код не мой, он взят откуда-то CodeProject, я извиняюсь я не помню точно, откуда и автор
