Rakesh R commented on BOOKKEEPER-391:
-------------------------------------

bq. During the meeting we talked about this issue
I hope the discussion went well. Wish you all the best for your dev efforts.

bq. Can you explain more deeply the purpose of having a special entry for the 
Auditor ?
AutoRecovery is meant for replication purpose and iirc, this is designed as an 
admin operated service. BK supports to start AutoRecovery service in either 
embedded mode or start 
[AutoRecovery|https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/bin/bookkeeper#L207]
 as a separate process. Since this is designed as an admin operated service, 
I'd prefer to provide a provision to configure his own credentials rather than 
using a normal bookkeeper client's credentials. If admin wants to use same 
bookkeeper client's credentials to AutoRecovery then he could take a call and 
configure the same in {{BookieAuditor}} principal entries section. Does this 
makes sense to you?

> This JIRA to discuss authentication mechanism of bookie clients and server. 
> Assume ZK provides fully secured communication channel using Kerberos based 
> authentication and authorization model. We could also manage and renew users 
> authenticated to BK via Kerberos. There is currently no configuration or 
> hooks for the Bookie process to obtain Kerberos credentials.
> Today an unauthenticated bookie client can easily establish connection with 
> the bookkeeper server.
