The following code shows how to set this property.

// Create a service host.
Uri httpUri = new Uri("http://localhost/Calculator");
ServiceHost sh = new ServiceHost(typeof(Calculator), httpUri);

// Create a binding that uses Windows security.
WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);
b.Security.Message.ClientCredentialType = MessageCredentialType.Windows;

// Get a reference to the authentication object.
X509ClientCertificateAuthentication myAuthProperties =
// Configure IncludeWindowsGroups.
myAuthProperties.IncludeWindowsGroups = true;
' Create a service host.
Dim httpUri As New Uri("http://localhost/Calculator")
Dim sh As New ServiceHost(GetType(Calculator), httpUri)

' Create a binding that uses Windows security.
Dim b As New WSHttpBinding(SecurityMode.Message)
b.Security.Message.ClientCredentialType = MessageCredentialType.Windows

' Get a reference to the authentication object.
Dim myAuthProperties As X509ClientCertificateAuthentication = _
' Configure IncludeWindowsGroups.
myAuthProperties.IncludeWindowsGroups = True

The property can also be set in a configuration file.

     <authentication mapClientCertificateToWindowsAccount='true'/>  


When using the certificate client credential type on bindings, the certificate is not mapped to Windows accounts. You can override this behavior using this property. When this property is set to true, it causes the identity from the client certificate to be mapped to a Windows account.
