So that when someone on a linux machine writes to disk and they open
it up on a windows machine it will show it was written by the same
person. (or vise versa)

Anyways it is a bit more complicated as I know objectSid it is in
base64 not just hex so I'll have to do a little more work than I
though. It is however a fun exercise.

I don't know about you but I use RFC2307
it doesn't matter what the SID is for it to map to my linux machines.
