Hi, I've got two bugs open because ACL inheritance does not work on NFSv4. See https://bugzilla.samba.org/show_bug.cgi?id=5446 (https://bugzilla.samba.org/show_bug.cgi?id=5447 pro forma for samba 3.0) So if you need ACL inhertance, you'll probaby want to apply the simple ptahces to vfs_zfsacl.c Nils
