IV74578: MECHLISTMIC SHOULD BE EMPTY WHEN GSS_S_COMPLETE IS SET.

Error description

• Error Message: SPNEGO client application failed to authenticate
  due to incorrect mechlistMIC.
  .
  Stack Trace: N.A.
  .
  

Local fix

Problem summary

• According to RFC 4178, no mechlistMIC is produced and
  mechlistMIC is not processed if one is provided;
  if the initiator sends the last mechanism token, the acceptor
  will send back a negotiation token with an accept_complete state
  and no mechlistMIC token.
  IBM's current implementation sends a non-empty mechlistMIC to
  the initiator.
  

Problem conclusion

• Send a empty mechlistMIC back to the initiator in the
  negotiation token.
