SPNEGO is a strange beast.

I have never personally built a (lib)curl for SPNEGO, and I've never had
access to a server that would allow me to try it.

I don't know of many users that use it and I'm not at all sure it still works
as supposed, due to all these circumstances and the fact that we develop curl
at a fairly high pace and features that aren't tested and "nursed" properly
tend to drop off and get left behind.

I'm afraid that the best way to get SPNEGO running is to roll up your sleeves
and dig into the code. Make sure the correct logic is performed for the given

Oh, and if you have questions or suggestions on the implementation I think the
curl-library may be the better mailing list to take those to.
