Hi Kai

It seems to be working for us at least. We've added the posix attrs and 
classes as defined in the ms schema to our s4 domain users and groups:
The mapping works fine over nfs4 for our Linux clients:-)

I was just wandering how s4 decides what the next xid will be before it 
writes a sid and xid entry to idmap.ldb. This was mainly to ease the 
readability of our posix scripts and tidy up idmap.ldb when e.g. a user 
is deleted.

Do you know where I could find that bit in the source?
