How to show/hide password box when not authenticated

[Webmaster]

I would like to have the username and password box show up when they have not been authenticated on the website and then I would like them to disappear when they have been authenticated and an active session exists after which time the search box should be the only editable box on the toolbar. If the session times out I would like the username and
password boxes to re-appear.

You can use Dynamic XML for this - you can make a script on your site
that generates include_xml file for toolbar. The file will depend on
login state: it will have username/password boxes and login
button if user is not logged and logout button if user is logged in.
