NAME¶vfs_acl_xattr - Save NTFS-ACLs in Extended Attributes (EAs)
vfs objects = acl_xattr
DESCRIPTION¶This VFS module is part of the samba(7) suite.
The vfs_acl_xattr VFS module stores NTFS Access Control Lists (ACLs) in Extended Attributes (EAs). This enables the full mapping of Windows ACLs on Samba servers.
The ACLs are stored in the Extended Attribute security.NTACL of a file or directory. This Attribute is not listed by getfattr -d filename. To show the current value, the name of the EA must be specified (e.g. getfattr -n security.NTACL filename).
This module forces the following parameters:
This module is stackable.
OPTIONS¶acl_xattr:ignore system acls = [yes|no]
If acl_xattr:ignore system acls is set to yes, the following additional settings will be enforced:
acl_xattr:default acl style = [posix|windows|everyone]
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.
