// 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.
