Well, in short, in the (now free downloadable) SFU 3.5 there is a NIS bridge, which exposes accounts and groups to NIS compliant machines. After installing SFU, your credentials management console shows a tab with tipical UNIX/POSIX attributes and files have an attrribute tab with rwxrvxrvx... It seems that the design of IFS subsystem assumes a superset of every known fs available about 1990.
Hmmm, yea. That's basicly what I think of the wohle thing. It should be possible for an IFS or another part to do a 1:1 or a 100:90 mapping of rights and users <-> SIDs
In my opinion there'S nothing to it to limit the user-part of SIDs to 16-bit and cut out just that.
PS. My favorite is still JFS. It has been prooved on OS/2 and OS/2 is our next relative. Its Src is open(GPL) and it supports most of the features. Even reparse points can be transparently implemented (EAs). I have nothing against s.o. implementing NTFS, but I see many problems. So cut & off
