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_tdb</command> VFS module stores
33 NTFS Access Control Lists (ACLs) in a tdb file.
34 This enables the full mapping of Windows ACLs on Samba
39 The ACL settings are stored in
40 <filename>$LOCKDIR/file_ntacls.tdb</filename>.
44 This module forces the following parameters:
46 <listitem><para>inherit acls = true</para></listitem>
47 <listitem><para>dos filemode = true</para></listitem>
48 <listitem><para>force unknown acl user = true</para></listitem>
52 <para>This module is stackable.</para>
56 <title>OPTIONS</title>
59 <!-- please keep in sync with the other acl vfs modules that provide the same options -->
61 <term>acl_tdb:ignore system acls = [yes|no]</term>
64 When set to <emphasis>yes</emphasis>, a best effort mapping
65 from/to the POSIX ACL layer will <emphasis>not</emphasis> be
66 done by this module. The default is <emphasis>no</emphasis>,
67 which means that Samba keeps setting and evaluating both the
68 system ACLs and the NT ACLs. This is better if you need your
69 system ACLs be set for local or NFS file access, too. If you only
70 access the data via Samba you might set this to yes to achieve
71 better NT ACL compatibility.
77 <term>acl_tdb:default acl style = [posix|windows]</term>
80 This parameter determines the type of ACL that is synthesized in
81 case a file or directory lacks an
82 <emphasis>security.NTACL</emphasis> xattr.
85 When set to <emphasis>posix</emphasis>, an ACL will be
86 synthesized based on the POSIX mode permissions for user, group
87 and others, with an additional ACE for <emphasis>NT
88 Authority\SYSTEM</emphasis> will full rights.
91 When set to <emphasis>windows</emphasis>, an ACL is synthesized
92 the same way Windows does it, only including permissions for the
93 owner and <emphasis>NT Authority\SYSTEM</emphasis>.
96 The default for this option is <emphasis>posix</emphasis>.

107 <para>The original Samba software and related utilities
108 were created by Andrew Tridgell. Samba is now developed
109 by the Samba Team as an Open Source project similar
110 to the way the Linux kernel is developed.</para>
