Now get_des_key seems to work correctly, but v5 authentication sometimes
gets a v4 salted key, which doesn't work for win2k machines, because
you're not applying the same care in getting des keys for v5 as for v4.
I'd guess the right answer to this is to duplicate the code in
get_des_key, modify so keys of only the desired enctype can get retrieved,
and call it for des etypes.
I should be following up shortly with a patch which does this. I can't see
any way around it
