// The nsAuthGSSAPI class provides responses for the GSS-API Negotiate method
// as specified by Microsoft in draft-brezak-spnego-http-04.txt
/* Some remarks on thread safety ...
*
* The thread safety of this class depends largely upon the thread safety of
* the underlying GSSAPI and Kerberos libraries. This code just loads the
* system GSSAPI library, and whilst it avoids loading known bad libraries,
* it cannot determine the thread safety of the the code it loads.
*
* When used with a non-threadsafe library, it is not safe to simultaneously
* use multiple instantiations of this class.
*
* When used with a threadsafe Kerberos library, multiple instantiations of
* this class may happily co-exist. Methods may be sequentially called from
* multiple threads. The nature of the GSSAPI protocol is such that a correct
* implementation will never call methods in parallel, as the results of the
* last call are required as input to the next.
