Yeah, the only solution to be able to access files is that you map that
SID to a group and store an ACE for that group, this is one of the
reasons I crazily talk of unifying the UID and GID spaces into the GID
space :-)
At least for this kind of SIDs it seem there is no other way, and if we
think that any SID can become a sidHistory in time (as a previous normal
domain can be migrated to a new domain) then we are really back to
consider always adding a "user-group" ACE anyway.
