      GSS status code:

      GSS_S_COMPLETE    Successful completion

      GSS_S_CONTINUE_NEEDED Indicates that a token from the peer
                        application is required to complete the context,
                        and that gss_accept_sec_context must be called
                        again with that token.

      GSS_S_DEFECTIVE_TOKEN Indicates that consistency checks
                        performed on the input_token failed.

      GSS_S_DEFECTIVE_CREDENTIAL Indicates that consistency checks
                        performed on the credential failed.

      GSS_S_NO_CRED The supplied credentials were not valid for
                        context acceptance, or the credential handle
                        did not reference any credentials.

      GSS_S_CREDENTIALS_EXPIRED The referenced credentials have
                        expired.

      GSS_S_BAD_BINDINGS The input_token contains different channel
                        bindings to those specified via the
                        input_chan_bindings parameter.

      GSS_S_NO_CONTEXT Indicates that the supplied context handle did
                       not refer to a valid context.

      GSS_S_BAD_SIG    The input_token contains an invalid signature.

      GSS_S_OLD_TOKEN   The input_token was too old.  This is a fatal
                        error during context establishment.

      GSS_S_DUPLICATE_TOKEN The input_token is valid, but is a
                        duplicate of a token already processed.  This
                        is a fatal error during context establishment.

3.5. gss_process_context_token

      OM_uint32  gss_process_context_token (
                     OM_uint32 *     minor_status,
                     gss_ctx_id_t    context_handle,
                     gss_buffer_t    token_buffer)

   Purpose:

   Provides a way to pass a token to the security service.  Usually,
   tokens are associated either with context establishment (when they
   would be passed to gss_init_sec_context or gss_accept_sec_context) or
   with per-message security service (when they would be passed to
   gss_verify or gss_unseal).  Occasionally, tokens may be received at
   other times, and gss_process_context_token allows such tokens to be
   passed to the underlying security service for processing.  At
   present, such additional tokens may only be generated by
   gss_delete_sec_context.  GSSAPI implementation may use this service
   to implement deletion of the security context.

   Parameters:

      context_handle    gss_ctx_id_t, read
                        context handle of context on which token is to
                        be processed

      token_buffer      buffer, opaque, read
                        pointer to first byte of token to process
