So when the slave notices that the master is back up, besides (and 
before) restarting ldap it has to drop the "virtual" IP, right?  I'd 
guess that the HA stuff should handle that.  But if LDAP knows it's 
master when it has the IP the IP has to go away before it will be slave.

If you can make the config files very similar, maybe LDAP doesn't need 
to know whether it's master or slave.
