Experimental module in the Samba software
vfs_acl_xattr[1]
is an experimental VFS-module[2] of Samba.
It stores NTFS Access-Control List (ACLs) in Extended Attributes (EAs), in
addition[3]
to storing them in Unix ACLs. This improves compatibility with Windows ACLs, because it allows to store all flags that can be used in Windows ACLs.[4]
