Let me rephrase: ZFS only supports NFSv4 ACLs, it does not support
POSIX.1e ACLs.  Since ACLs are not a mandatory element of filesystem,
sharing ZFS over NFSv3 works, but the client has no way to manipulate
the ACLs or retrieve them.  When sharing ZFS over NFSv4, the NFSv4 ACLs
should work, I guess.

Still, I'm not sure if the problem is actually ACL-related.
