NegotiateStream::RemoteIdentity Property

Gets information about the identity of the remote party sharing this authenticated stream.

Namespace:  System.Net.Security
Assembly:  System (in System.dll)

virtual property IIdentity^ RemoteIdentity {
	IIdentity^ get ();

Property Value

Type: System.Security.Principal::IIdentity
An IIdentity object that describes the identity of the remote endpoint.


Authentication failed or has not occurred.

When accessed by the client, this property returns a GenericIdentity containing the Service Principal Name (SPN) of the server and the authentication protocol used. When accessed by the server, this property returns a WindowsIdentity that describes the client. If the WindowsIdentity is not available, client information is returned to the server in a GenericIdentity.

The following code example demonstrates displaying the value of this property.

   static void EndAuthenticateCallback( IAsyncResult^ ar )

      // Get the saved data.
      ClientState^ cState = dynamic_cast<ClientState^>(ar->AsyncState);
      TcpClient^ clientRequest = cState->Client;
      NegotiateStream^ authStream = dynamic_cast<NegotiateStream^>(cState->AuthStream);
      Console::WriteLine( L"Ending authentication." );

      // Any exceptions that occurred during authentication are 
      // thrown by the EndServerAuthenticate method. 

         // This call blocks until the authentication is complete.
         authStream->EndAuthenticateAsServer( ar );
      catch ( AuthenticationException^ e ) 
         Console::WriteLine( e );
         Console::WriteLine( L"Authentication failed - closing connection." );
      catch ( Exception^ e ) 
         Console::WriteLine( e );
         Console::WriteLine( L"Closing connection." );

      // Display properties of the authenticated client.
      IIdentity^ id = authStream->RemoteIdentity;
      Console::WriteLine( L"{0} was authenticated using {1}.", id->Name, id->AuthenticationType );
