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:

              •   inherit acls = true

              •   dos filemode = true

              •   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:

                  •   create mask = 0666

                  •   directory mask = 0777

                  •   map archive = no

                  •   map hidden = no

                  •   map readonly = no

                  •   map system = no

                  •   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.

           When set to posix, an ACL will be synthesized based on the POSIX mode permissions for
           user, group and others, with an additional ACE for NT Authority\SYSTEM will full
           rights.

           When set to windows, an ACL is synthesized the same way Windows does it, only
           including permissions for the owner and NT 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.
