Create a DTML document called logout at the top of your Zope tree 
which raises an unauthorized error.
<dtml-if ExUser>
   <dtml-if "ExUser==_.str(AUTHENTICATED_USER)">
      <dtml-raise type="Unauthorized">
         You have been logged out.
      </dtml-raise>
   <dtml-else>
      <dtml-var "RESPONSE.redirect('index_html')">
   </dtml-if>
<dtml-else>
   <dtml-var "RESPONSE.redirect('logout?ExUser=%s' % 
AUTHENTICATED_USER)">
</dtml-if>

Now you can have a logout link or whatever at 
http://host/somepath/logout. The only catch is that once you hit it 
you *must* use a different userid as the current one will be rejected 
unconditionally. When you do enter a new userid you get redirected 
to the index_html at the current level. An empty string works as well 
instead of 'index_html' if you prefer.
