Rakesh R commented on ZOOKEEPER-1045:
-------------------------------------

bq. Would we recommend that folks use the same credentials for 
Server/QuorumServer/QuorumClient? Or should they use different for each?

All three can use same credentials. I couldn't see any problem in sharing the 
credentials. But IMHO we can recommend to use different credentials for 
client-server(Server) and server-server 
communications(QuorumServer/QuorumClient) in order to clearly separate the 
communication paths. Whats your opinion?

For the previous comment, to avoid confusions about the "server client, should 
I modify {{QuorumClient}} to {{QuorumLearner}}?

> 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.
