So, what can I do? I need to use ACLs in Windows and the same on liunux 
server. I use ext4 fs on the linux server, but ext4 only support POSIX ACLs.
What should I do? Can I change the filesystem (e.g. ZFS) so that I can 
use the NT ACLs in linux or should I try s3compat? I also have to use 
the NT ACLs  via NFS. Any idea?
