[Samba] NFSv4 acls inheritance flags

NFSv4 acls works nice on UFS except the inheritance flags, , i was planning to use vfs_acl_xattr and posix acls (XFS and ext4 on Linux) before, it works fine but when i set some permissions on shares from a Windows machine it takes too much time , on a share with around 30GB and 100000 files it takes around 20 minutes too apply permissions, is this normal ?

For filesystems that don't support nfsv4 acls you need to try to use vfs_acl_xattr. Most modern fs's support extended attributes, this combined with posix acl's, samba is able to map NTACLs and it doesn't confuse POSIX (e.g. NFSv3) clients as badly.

Hi people, 

I'm testing Samba 4.0.17 running as classic pdc mode under FreeBSD 10 and 9.2 , all shares are on ZFS volumes, i would like to use UFS instead of ZFS , but according the wiki page https://wiki.freebsd.org/NFSv4_ACLs nfsv4 inheritance flags works only with ZFS , i tried the parameters inherit acls and inherit permissions with module vfs_zfsacl on the UFS shares but got no success , are they work for NFSv4 acls or only POSIX ?
