Patch For sspi.c To Use Windows Authentication

A user on my TinyTDS/SQLServer list reported this bug with FreeTDS. They could not get Windows authentication to work and had to make the following change to sspi.c

>  free(auth_buf);
> // code added start
>  if (status == SEC_I_COMPLETE_AND_CONTINUE || status == SEC_I_CONTINUE_NEEDED) {
>   if (out_buf.cbBuffer > 0)
>   {
>    tds_put_n(tds, auth->tds_auth.packet, out_buf.cbBuffer);
>    tds_flush_packet(tds);
>    return status;
>   }
>  }
> // code added end
>  if (status != SEC_E_OK)
>   return TDS_FAIL;

After that change, they got Windows authentication working and saw the following FreeTDS debug info.

> AUTH
> ENVCHANGE
> INFO
> ENVCHANGE
> ENVCHANGE
> INFO
> LOGINACK
> ENVCHANGE
> DONE
> Finally, there is the LOGINACK and DONE tokens : )

Opinions on doing this patch?
