zfs discuss - Jun 2008 - ZFS and ACL''s over NFSv3

Can someone please clarify the ability to utilize ACL''s over NFSv3 from
a ZFS share?  I can "getfacl" but I can''t
"setfacl".  I can''t find any documentation in this regard. 
My suspicion is that that ZFS Shares must be NFSv4 in order to utilize ACLs but
I''m hoping this isn''t the case.

Can anyone definitively speak to this?  The closest related bug I can find is
6340720 which simply says "See comments."

You can''t set NFSV4 ACLs over NFSv3, it only understands POSIX draft 
ACLs.  When you see getfacl work that is only because it is fabricating 
an ACL based on the mode bits of the file.  Its not a real ACL.

Also, remember that NFSv3 doesn''t officially support ACLs.  Sun
provided
a sideband protocol to deal with UFS POSIX Draft ACLs, but its not part 
of the official protocol.
