IsMutuallyAuthenticated Property

NegotiateStream.IsMutuallyAuthenticated Property

Gets a Boolean value that indicates whether both the server and the client have been authenticated.

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

public override bool IsMutuallyAuthenticated { get; }

Property Value

Type: System.Boolean
true if the server has been authenticated; otherwise, false.

Mutual authentication is specified by the client when the client wants the server to provide credentials for authentication. By default, clients request mutual authentication.

The Negotiate protocol selects either NTLM or Kerberos depending on the security protocols supported by the client and server. NTLM does not support mutual authentication.

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


 static void DisplayAuthenticationProperties(NegotiateStream stream)
{
     Console.WriteLine("IsAuthenticated: {0}", stream.IsAuthenticated);
    Console.WriteLine("IsMutuallyAuthenticated: {0}", stream.IsMutuallyAuthenticated);
    Console.WriteLine("IsEncrypted: {0}", stream.IsEncrypted);
    Console.WriteLine("IsSigned: {0}", stream.IsSigned);
    Console.WriteLine("ImpersonationLevel: {0}", stream.ImpersonationLevel);
    Console.WriteLine("IsServer: {0}", stream.IsServer);
}
