There is a little back story in this old post, but here is the gist.

We have a web application that uses PKI certs to control user access. 
Typically, we use custom JSTL libs to verify the user has the proper roles to 
access the requested .jsp. However, this forces us to include 
authentication/authorization code into every page, which isn't the best 
solution. 

Instead, we'd like to handle this in the application server (JBoss 4.2.2 in our 
case). We already use a security domain for EJBs and we'd like to extend this 
to the web tier.

My attempt at doing this (see old post) had a few problems, but that was mostly 
just developer error. However, since then, I had problems forcing the users 
request to authenticate via the JAAS process on each web request. 
For example, a user would go to http://jboss/secure/secure.jsp, and his 
certificate would be passed to my custom login module via HTTP header and the 
user would be authenticate. However, if the user then requested 
http://jboss/secure2.jsp, the custom login module would not be accessed. This 
seemed to be because JBoss caches login credentials. 

That page recommends setting the default cache timeout to 0, in order to force 
authentication/authorization each time. While this does work for the web 
requests, it breaks our EJBs. If, for example, a servlet makes a single call to 
an EJB and then exits, it works fine. If we make a call to two EJBs, then it 
fails. 

It is possible that this is a bug in the JAAS code within JBoss (I can't seem 
to find the URLs/JIRA issue that relate at this time), but my bigger question 
is whether this is the best way to force each web request through an 
authentication and authorization process? For each request, we need to verify 
the user has the proper roles? Is this the best way to do it? Or is there any 
approach I should use?

Thanks...
