In Samba3, there is the afsacl vfs module (see source/modules/vfs_afsacl.c).
It can be used to support AFS ACLs on shares residing on AFS file systems.

It only helps if there is AFS underlying a share.
Otherwise it does not. :-)

If we don't care about other users of the file system, then we can
(or could) do even better than AFS and store full windows ACLs
in a separate database or extended attributes.
