    We also have requirements for redundancy and were not happy with
the single point of failure the Naming Service offers.
    One method was to write custom code to handle the synchronization
problems. Ugh.
    Our solution was to dump the Naming service altogether and use LDAP
instead. LDAP has replication capability, can handle disconnection, and
slave servers are updated when re-connection occurs.

    Easy. You get a COMM_FAILURE exception when that happens.
