and security model for local accounts' from 'Guest only - local users
authenticate as Guest' to 'Classic - local users authenticate as
themselves'. Disable the Guest account if applicable.

If the SAMBA daemon is running, double-check the SAMBA configuration
around guest user access and disable guest access if appropriate");
