I am trying to integrate iChain with the JBoss Portal. JBoss should take the credentials that iChain puts into the http-request and use these to determine the logged in user. I think I would need to provide a customization at the point in the request serving process where the portal looks up the remote user.
Is there documentation how to plug in your own implementation? Has someone else tried to implement something similar?
I looked into using a LoginModule, but this is only activated after the user supplied username and password, and with using iChain the user could be logged in as soon as he accesses the portal.
