AuthNegotiate#
HTTP-based GSS-Negotiate authentication, as defined by RFC 4559.
Sessions do not support this type by default; if you want to
enable support for it, call 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 supported to see if it
was.
