Alexander Shraer commented on ZOOKEEPER-1045:
---------------------------------------------
Rakesh, I will try to take a look more closely soon, so maybe I'm
missunderstanding. But to your question - during a reconfig, zoo.cfg is only
updated to point to a new dynamic configuration file. That new file contains
the up-to-date server list, zoo.cfg only contains a pointer. This update
happens during the configuration commit. But authorization should probably
happen before, maybe when a reconfig is processed or maybe even before that -
when a new server boots and tries to connect to the leader. Does the leader
check new server connections ? If that server wasn't initially declared, would
it be able to connect ?

> ZOOKEEPER-938 addresses mutual authentication between clients and servers.
> This bug, on the other hand, is for authentication among quorum peers.
> Hopefully much of the work done on SASL integration with Zookeeper for
> ZOOKEEPER-938 can be used as a foundation for this enhancement.
