title: Accessing a SPNEGO authenticated webservice from C#
body: <p>We have a web service that serves data over HTTP and authenticates users via SPNEGO (and single sign-on). We want to write a C# client for this web service. </p>
  
  <p>Is there any standard/provided way in .NET of generating the necessary token? Extensive Googling suggests that there is no native support for SPNEGO.</p>
