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)

Public Overridable ReadOnly Property RemoteIdentity As IIdentity

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.

Public Shared Sub EndAuthenticateCallback(ByVal ar As IAsyncResult)
    ' Get the saved data.
    Dim cState As ClientState = CType(ar.AsyncState, ClientState)
    Dim clientRequest As TcpClient = cState.Client
    Dim authStream As NegotiateStream = CType(cState.AuthenticatedStream, NegotiateStream)
    Console.WriteLine("Ending authentication.")
    ' Any exceptions that occurred during authentication are
    ' thrown by the EndAuthenticateAsServer method.
        ' This call blocks until the authentication is complete.
    Catch e As AuthenticationException
        Console.WriteLine("Authentication failed - closing connection.")
    Catch e As Exception
        Console.WriteLine("Closing connection.")
    End Try
    ' Display properties of the authenticated client.
    Dim id As IIdentity = authStream.RemoteIdentity
    Console.WriteLine("{0} was authenticated using {1}.", id.Name, id.AuthenticationType)

End Sub
