Oh yes, we've had POSIX ACL support for a *long*
time. I can't remember exactly what the earliest
version was (probably a 2.2.x version).

However we've been slowly getting better over
the years in doing the ACL mapping, culminating
with the extra Windows ACL layer stored in EA's
we now have that provides a 100% Windows compatible
protocol response to the client, but then is mapped
onto POSIX ACLs for filesystems that can't store
native (or NFSv4) ACLs.
