What I forgot to mention: LoginManager is a Zope product that is built 
using ZPatterns, another Zope product.

When you are doing advanced things with LoginManager, you need to know 
how ZPatterns works.

There are a couple of HOWTO documents on using LoginManager. It will be 
only a small change to alter the "userRoles" method that returns the 
roles a user should have to calculate these roles based on other criteria.

See these documents for information about how to set up LoginManager.
