[Zope] dtml sessions

[Dennis Allison]

Ah ha!  you have as method that is supposed to be private to a particular 
user.   You should set the view permission for the method to be 
"Authorized User" and have the method test for the particular user and 
do nothing if the current user is not the right one.

A more general mechanism would be to create a local role for privileged 
users and set the view permission for the dtml-method to be that role.  
The you can give any user that role in acl_users and they will 
automagically have access rights to that method.

Good web design suggests that the navigation to this special method be 
controlled by the role as well so there's no button to push if the user
is not allowed to push the button.
