For 2.0 should we _stop_ supporting the CAS module in favor of buji-pac4j (which uses Shiro).
We seem to be leaning that way: https://issues.apache.org/jira/browse/SHIRO-402 If that is the path we want to go down, I'm guessing the migration path would be mostly just be shiro.ini changes (and obviously a few dependencies). I personally have not use the CAS realm or buji-pac4j, so if I'm way off this please chime in. -Brian
