Master/Slave with a heartbeat failover.  Turn off the heartbeat on the
master and the slave takes over the shared address.  wait a minute or so
for existing queries to finish on the master before killing off the
process.  No service interruption.

OpenLDAP 2.0 doesn't have entryUUID so that's not a problem (yet).  As I
progress with developing the rollout of 2.1, I expect to modify my perl
code to create the entryUUID's as well (it already creates the
creat*/modif* attributes when it creates a new entry) -- I also expect
slapcat (as the documentation of this hasn't changed) to continue to
blindly put in whatever I give it.  Since the ldif I'm loading already
will have entryUUID attributes, I don't expect slapcat to be creating
them, just honoring what's there...
