4 - Is Java JaaS only able to manage/persist tickets for the Default principal in the cache? - Or how do I manage with JaaS a situation where I have tickets for a lot of principals in a single cache file?

I found no simple way to manage collections (it's quite a recent standard), my personal choice is to create one cache file per principal.
