How do you integrate JAAS with orion security?

[Harley Rana]

I have been looking into the JAAS security for building a more flexible
security framework.
The main problem I have is how to use the jaas api with the security
features in Orion.
For example if you implement a custom LoginModule, how does it add a
principal to the Orion web container, or how does jaas register a user for
method permissions in an EJB?

Is there a way to integrate with the Orion security model with jaas?
Thanks for your help!
