This is what I have on 3.3.1. To me this documentation seriously needs expanded.

NAME
       vfs_acl_xattr - Save NTFS-ACLs in Extended Attributes (EAs)

SYNOPSIS
       vfs objects = acl_xattr

DESCRIPTION
       This VFS module is part of the samba(7) suite.

       The vfs_acl_xattr VFS module stores NTFS Access Control Lists
       (ACLs) in Extended Attributes (EAs). This enables the full mapping
       of Windows ACLs on Samba servers.

       The ACLs are stored in the Extended Attribute security.NTACL of a
       file or directory. This Attribute is not listed by getfattr -d
       filename. To show the current value, the name of the EA must be
       specified (e.g.  getfattr -n security.NTACL filename ).

       Please note that this module is experimental!

       This module is stackable.

OPTIONS
       There are no options for vfs_acl_xattr.

       Open Source project similar to the way the Linux kernel is
       developed.
