Patrick Hunt commented on ZOOKEEPER-1045:
-----------------------------------------
bq. if somebody else owns host2.example.com they can get principals for those
same service types on their host. At least in our environment
I see. That's very useful information that I wasn't aware of. Thanks Jason.
bq. Kerberos clients typically compute the credential name they expect the
server to use based on the hostname that the client is connecting to, so folks
in a Kerberos environment will typically have a functioning name service like
DNS.
so in this case we'd expect the host names to all match? zoo.cfg/kerberos/dns.
I think that's reasonable.
[~rakeshr] - is that what you found when looking at the Hadoop code? Your
comment earlier about "InetAddress.getLocalHost().getCanonicalHostName()" being
used.

> 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.
