    NTLM has been introduced since Java, PHP and other non-microsoft programming environments don't have full support for SPNego. With the proper setting, SPNego use Kerberos authentication and falls back to NTLM if Kerberos fails, that's why usually the following line in CustomSetting.config file, in order to support both ways:

    <add key="WebServicesUseNTLMAuthentication" value="false">

    Hi, Thanks for quick reply.

    With below setting, this will allow all clients ( Win8 app ( Win store app) , Desktop Clients and other clients) to access NAV?

     <!--

     Turns on or off NTLM authentication protocol for Web Services

         false: Use SPNEGO (recommended)

         true: Use NTLM only

     -->

       <add key="WebServicesUseNTLMAuthentication" value="false"></add>

    This setup will allow to instantiate connections to NAV in Java/PHP, desktop client connection is managed by ClientCredentialType parameter (Window = active directory credential or UserName = insert user name and password required).

    Are you running NAV 2009 R2?
