| 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
|
|---|
| 35 | servers.
|
|---|
| 36 | </para>
|
|---|
| 37 |
|
|---|
| 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>

|

| 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.
