Let's suppose that you have an application server and a DB server
running on the same node. That turns out to be too much load, so you
move the application server to a separate machine and connect the two
machines with a crossover cable, or a VLAN that has nothing else on
it. To me, it's quite sane to want connections on that network to
proceed without authentication or authorization. If you've got to
open up the database more than that then, yes, you need authentication
and authorization.
