|
|---|
| 2 | <a class="citerefentry" href="samba.7.html"><span class="citerefentry"><span class="refentrytitle">samba</span>(7)</span></a> suite.</p><p>The <code class="literal">vfs_acl_xattr</code> VFS module stores
|
|---|
| 3 | NTFS Access Control Lists (ACLs) in Extended Attributes (EAs).
|
|---|
| 4 | This enables the full mapping of Windows ACLs on Samba
|
|---|
| 5 | servers.
|
|---|
| 6 | </p><p>The ACLs are stored in the Extended Attribute
|
|---|
| 7 | <em class="parameter"><code>security.NTACL</code></em> of a file or directory.
|
|---|
| 8 | This Attribute is <span class="emphasis"><em>not</em></span> listed by
|
|---|
| 9 | <code class="literal">getfattr -d <code class="filename">filename</code></code>.
|
|---|
| 10 | To show the current value, the name of the EA must be specified
|
|---|
| 11 | (e.g. <code class="literal">getfattr -n security.NTACL <code class="filename">filename</code>
|
|---|
| 12 | </code>).
|

|

| 14 | When set to <span class="emphasis"><em>yes</em></span>, a best effort mapping
|
|---|
| 15 | from/to the POSIX ACL layer will <span class="emphasis"><em>not</em></span> be
|
|---|
| 16 | done by this module. The default is <span class="emphasis"><em>no</em></span>,
|
|---|
| 17 | which means that Samba keeps setting and evaluating both the
|
|---|
| 18 | system ACLs and the NT ACLs. This is better if you need your
|
|---|
| 19 | system ACLs be set for local or NFS file access, too. If you only
|
|---|
| 20 | access the data via Samba you might set this to yes to achieve
|
|---|
| 21 | better NT ACL compatibility.
