Eugene Koontz commented on ZOOKEEPER-938:
-----------------------------------------
As Botond mentioned in ZOOKEEPER-896, Zookeeper clients that use Kerberos must
be able to handle mutual authentication with more than one Zookeeper server,
and also must cope with ticket expiry. The sasl.patch of 2011-01-10 03:57 PM
does not handle either of these circumstances. I'll be studying Botond's C
client patch to ZOOKEEPER-896 to learn how it might apply to the Java client.

> Support Keberos authentication of clients.
> The following usage would let an admin use Kerberos authentication to assign
> ACLs to authenticated clients.
> 1. Admin logs into zookeeper (not necessarily through Kerberos however).
> 2. Admin decides that a new node called '/mynode' should be owned by the user
> 'zkclient' and have full permissions on this.
> 3. Admin does: zk> create /mynode content kerb:zkcli...@foofers.org:x:cdrwa
> (note: for now, the dummy ':x' is a placeholder for the password, and is
> required by the zk command parser. The user's actual password is not stored
> within Zookeeper; simply put 'x' there.)
> 4. User 'zkclient' logins to kerberos using the command line utility 'kinit'.
> 5. User connects to zookeeper server using a Kerberos-enabled version of
> zkClient (ZookeeperMain).
> 6. Behind the scenes, the client and server exchange authentication
> information. User is now authenticated as 'zkclient'.
> 7. User accesses /mynode with permissions 'cdrwa'.
