// The nsNegotiateAuth class provides responses for the GSS-API Negotiate method
// as specified by Microsoft in draft-brezak-spnego-http-04.txt

// It can also be configured to talk raw NTLM.  This implementation of NTLM has
// the advantage of being able to access the user's logon credentials.  This
// implementation of NTLM should only be used for single-signon.  It should be
// avoided when authenticating over the internet since it may use a lower-grade
// version of password hashing depending on the version of Windows being used.
