You can prevent this from happening if you forbid users to change the
ACL and enforce inheritance. That's the reason I can't give those files
sensible POSIX permissions since they'd need to be translated into ACL
which I can't write. All our filers are set up that way. No I don't
think this is a good idea, but I guess there'd been one support call too
many with a share that somebody made inaccessible by fiddling with the
ACL.
