-----------------------------------------
Eugene,
Sorry I have been late in reviewing this, but I think this should definitely
go into 3.4 release.
One thing though, how does the zkclient authenticate via the client API?
The user does kinit and then? How do we handle client credential expiry?
Can you please layout a detailed design on this? I would really like this in
3.4 but am a novice on kerberos and would be lost without a design.

> 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'.
