Ionel,
You can implement your own loggin module and/or use a database JAAS login
module.
>From there, it is up to you to organize the security data in the DB as you
wish (with other DB tables that, for example, map a given user to a set of
functions/features/frames he has access to, etc.) Then, you can create a
bean that will query this database (the same used by JAAS) to give you with
this additional information.
Cheers,
Sacha
