26 <title>DESCRIPTION</title>
28 <para>This VFS module is part of the
29 <citerefentry><refentrytitle>samba</refentrytitle>
30 <manvolnum>7</manvolnum></citerefentry> suite.</para>
32 <para>The <command>vfs_acl_xattr</command> VFS module stores
33 NTFS Access Control Lists (ACLs) in Extended Attributes (EAs).
34 This enables the full mapping of Windows ACLs on Samba
38 <para>The ACLs are stored in the Extended Attribute
39 <parameter>security.NTACL</parameter> of a file or directory.
40 This Attribute is <emphasis>not</emphasis> listed by
41 <command>getfattr -d <filename>filename</filename></command>.
42 To show the current value, the name of the EA must be specified
43 (e.g. <command>getfattr -n security.NTACL <filename>filename</filename>
47 <para>This module is stackable.</para>
51 <title>OPTIONS</title>
54 <!-- please keep in sync with the other acl vfs modules that provide the same options -->
56 <term>acl_xattr:ignore system acls = [yes|no]</term>
59 When set to <emphasis>yes</emphasis>, a best effort mapping
60 from/to the POSIX ACL layer will <emphasis>not</emphasis> be
61 done by this module. The default is <emphasis>no</emphasis>,
62 which means that Samba keeps setting and evaluating both the
63 system ACLs and the NT ACLs. This is better if you need your
64 system ACLs be set for local or NFS file access, too. If you only
65 access the data via Samba you might set this to yes to achieve
66 better NT ACL compatibility.
77 <para>The original Samba software and related utilities
78 were created by Andrew Tridgell. Samba is now developed
79 by the Samba Team as an Open Source project similar
80 to the way the Linux kernel is developed.</para>
