NAME

6       vfs_acl_tdb - Save NTFS-ACLs in a tdb file
7

SYNOPSIS

9       vfs objects = acl_tdb
10

DESCRIPTION

12       This VFS module is part of the samba(7) suite.
13
14       The vfs_acl_tdb VFS module stores NTFS Access Control Lists (ACLs) in a
15       tdb file. This enables the full mapping of Windows ACLs on Samba
16       servers.
17
18       The ACL settings are stored in $LOCKDIR/file_ntacls.tdb.
19
20       This module forces the following parameters:
21
22              •   inherit acls = true
23
24              •   dos filemode = true
25
26              •   force unknown acl user = true
27
28
29       This module is stackable.

OPTIONS

32       acl_tdb:ignore system acls = [yes|no]
33           When set to yes, a best effort mapping from/to the POSIX ACL layer
34           will not be done by this module. The default is no, which means
35           that Samba keeps setting and evaluating both the system ACLs and
36           the NT ACLs. This is better if you need your system ACLs be set for
37           local or NFS file access, too. If you only access the data via
38           Samba you might set this to yes to achieve better NT ACL
39           compatibility.
40
41           If acl_tdb:ignore system acls is set to yes, the following
42           additional settings will be enforced:
43
44                  •   create mask = 0666
45
46                  •   directory mask = 0777
47
48                  •   map archive = no
49
50                  •   map hidden = no
51
52                  •   map readonly = no
53
54                  •   map system = no
55
56                  •   store dos attributes = yes
57
58
59       acl_tdb:default acl style = [posix|windows|everyone]
60           This parameter determines the type of ACL that is synthesized in
61           case a file or directory lacks an security.NTACL xattr.
62
63           When set to posix, an ACL will be synthesized based on the POSIX
64           mode permissions for user, group and others, with an additional ACE
65           for NT Authority\SYSTEM will full rights.
66
67           When set to windows, an ACL is synthesized the same way Windows
68           does it, only including permissions for the owner and NT
69           Authority\SYSTEM.
70
71           When set to everyone, an ACL is synthesized giving full permissions
72           to everyone (S-1-1-0).
73
74           The default for this option is posix.
