-----------------------------------------
Hi Benjamin,
Unfortunately I couldn't find support for obtaining the default Kerberos realm
in java.security or javax.security.
(In fact, it seems that javax.security uses sun.security internally, for
example:
http://www.java2s.com/Open-Source/Java-Document/6.0-JDK-Core/security/javax/security/auth/kerberos/KerberosPrincipal.java.htm.
(see "import sun.security.krb5.Asn1Exception;" in the source code)).
So I don't see any way around using the sun.* classes.

> Support Kerberos 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 sasl:[email protected]:cdrwa
> 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'.
