Reproduce the issue on Droidwall 1.5.7 by enabling Password, adding the desktop widget, and invoking the firewall action. Trace the password-protected path used by the widget and compare it with the normal firewall action; done means the widget presents a password prompt and then allows enabling or disabling the firewall.
