WCF Service - MTOM Security modes & transport/message property's values

Could you please let me know, how/what to set the Mode and ClientCredentialType property in configuration for MTOM-basicHttpBinding.

For ANONYMOUS authentication- Below configuration is working fine

<security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
</security>

Could you please help me to understand what should the values against each attribute for NTLM and Windows authentication types for Mtom binding?

Thanks,

Both the below security modes support Windows/NTLM authentication and MTOM encoding.

Uri uri = new Uri("https://localhost:21011");
  BasicHttpBinding binding = new BasicHttpBinding();
            binding.MessageEncoding = WSMessageEncoding.Mtom;
            binding.Security.Mode = BasicHttpSecurityMode.Transport;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
            // NTLM
            //binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;

Or,

Uri uri = new Uri("http://localhost:21011");
            BasicHttpBinding binding = new BasicHttpBinding();
            binding.MessageEncoding = WSMessageEncoding.Mtom;
            binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;

Feel free to let me know if the problem still exists.
