KNOWN_BUGS #10:

   To get HTTP Negotiate authentication to work fine, you need to provide a
   (fake) user name (this concerns both curl and the lib) because the code
   wrongly only considers authentication if there's a user name provided.
   http://curl.haxx.se/bug/view.cgi?id=1004841.

So you need to use something like "-u fake:fake" to trigger it.
