SoupAuthNegotiate

HTTP-based GSS-Negotiate authentication, as defined by RFC 4559.

SoupSessions do not support this type by default; if you want to enable support for it, call soup_session_add_feature_by_type(), passing SOUP_TYPE_AUTH_NEGOTIATE.

This auth type will only work if libsoup was compiled with GSSAPI support; you can check soup_auth_negotiate_supported() to see if it was.
