This document is a companion to the SPNEGO HTTP authentication document, as specified in [RFC4559]. It uses the augmented Backus-Naur Form (BNF), as described in [RFC4559], section 4, and relies on both the non-terminals defined in that document and other aspects of the specification HTTP/1.1, as specified in [RFC2617]. For more information, see [RFC2616].
