> Starting up a node with {{-Dcassandra.join_ring=false}} in a cluster that has authentication
configured, eg PasswordAuthenticator, won't be able to serve requests. This is because {{Auth.setup()}}
never gets called during the startup.
> Without {{Auth.setup()}} having been called in {{StorageService}} clients connecting
to the node fail with the node throwing
> {noformat}
> java.lang.NullPointerException
