Was wondering if there are any samples or tests for Geronimo that use role-based authentication for EJB methods?

More specifically, I was wondering how to configure the role mappings in the Geronimo deployment plan. Most of the samples out there revolve around the war, but I have not found anything relating to the EJB jar.

Thanks...

Chris
