NAME
vfs_acl_tdb - Save NTFS-ACLs in a tdb file
SYNOPSIS
vfs objects = acl_tdb
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_acl_tdb VFS module stores NTFS Access Control Lists (ACLs) in a
tdb file. This enables the full mapping of Windows ACLs on Samba
servers.
The ACL settings are stored in $LOCKDIR/file_ntacls.tdb.
This module forces the following parameters:
o inherit acls = true
o dos filemode = true
o force unknown acl user = true
This module is stackable.
OPTIONS
acl_tdb:ignore system acls = [yes|no]
When set to yes, a best effort mapping from/to the POSIX ACL layer
will not be done by this module. The default is no, which means
that Samba keeps setting and evaluating both the system ACLs and
the NT ACLs. This is better if you need your system ACLs be set for
local or NFS file access, too. If you only access the data via
Samba you might set this to yes to achieve better NT ACL
compatibility.
If acl_tdb:ignore system acls is set to yes, the following
additional settings will be enforced:
o create mask = 0666
o directory mask = 0777
o map archive = no
o map hidden = no
o map readonly = no
o map system = no
o store dos attributes = yes
acl_tdb:default acl style = [posix|windows|everyone]
This parameter determines the type of ACL that is synthesized in
case a file or directory lacks an security.NTACL xattr.
Authority\SYSTEM.
When set to everyone, an ACL is synthesized giving full permissions
to everyone (S-1-1-0).
The default for this option is posix.

Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
