I'm working on a suite of status and control applications for embedded devices 
based on JBoss. I want to leverage as much of the built-in security framework 
as I can. But, I'm having a hard time getting my mind wrapped around the 
capabilities. I've read the security section in "JBoss 4.0, the Official 
Guide." And I've played with example 2 in that chapter. On my first read, I 
thought that the Principal object in the LoginContext in my client would be 
updated with the information retrieved on the server side by the LoginModule. 
Specifically, I'd like to be able to query the LoginContext in my client after 
authentication to retrieve the user's Roles. But, after hacking example 2 a 
bit, it doesn't look like the client side LoginContext is being updated from 
the server side. I assume that would happen in a stand-alone JAAS application? 
But, JBoss hasn't fully implemented that functionality in the client\server 
architecture? This is unfortunate. In my client applications I want to be able 
to limit the user's choices in the UI to prevent them from requesting 
operations they don't have access to. For example, I may have admin users and 
normal operators. So, I wouldn't want my operators to see a bunch of widgets 
for admin functions. I'll need the user's list of Roles in the client for this. 
So, it would be ideal if the Principal in the client's LoginContext were 
updated with the information gathered by the server-side LoginModule. Is this 
supposed to happen and I just have a configuration problem? If this feature 
just isn't implemented, any thoughts towards implementing it some day? I have a 
few thoughts about a work-around to get what I need. Basically, I'll just have 
to publish a method from an EJB on the server to retrieve the Roles manually. 
But, I just wanted to check to make sure I'm not missing something before I go 
down that road.

Thanks in advance for any help or suggestions.

Eric
