     behavior is to use the unix mode specified when creating the directory. 
     Enabling this option sets the unix mode to 0777, thus guaranteeing that 
     default directory acls are propagated.
+
+    Note that using the VFS modules acl_xattr or acl_tdb which store native
+    Windows as meta-data will automatically turn this option on for any
+    share for which they are loaded, as they require this option to emulate
+    Windows ACLs correctly.
