I'm up to my elbows in ripping apart the ZMI to find the code, and its another basic idea, so I thought I'd throw it out to the list. How can I programatically (Python/Page Templates) clear the login information from the browser? That is - log someone out. Setting up the permisions with the LDAP users was straightforward, but at the moment all I can do is detect the lack of permissions and say "Access Unauthorized". The only way to switch users is to open a new browser. This, of course, is immature and - if you'll excuse the colloquialism - sucks hard. So I'd like to offer a button that says "Log me out". Amusingly, the Security chapter of The Zope Book does not seem to cover this. Maybe it shouldn't and I'm just easily amused. Thanks, Ed
