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.
