Another benefit is that failover occurs much more quickly when using a
floating IP managed with heartbeat compared to using multiple server
listings in your clients dns and ldap config files.  The default timeout
for EACH lookup is killer (if not using client side caching) when the
first server is down and the responses must come from the second one in
the list.
