Dejan and James, I'm looking at the JAAS plugins now and yes this approach for deriving the user and group from a certificate looks pretty clear, and this will save me a lot of time. Thanks!
Can either of you give me a similar guidance for how I would do the AuthorizationMap piece? It looks like I can simply implement AuthorizationMap, but the return type of Set<?> for the methods seems highly under-constrained. The comments say that the methods return ACLs, but its not obvious to me what forms the ACLs take. Looking at SimpleAuthorizationMap, I see that it is primarily delegating to DestinationMap, but DestinationMap (and its helper DestinationMapNode, DestinationMapEntry) is just complex enough that I haven't been able to figure it out from just browsing the code. I have a hunch that one of you can give me some quick pointers here that will also save me a lot of time.
