Dear Wessel, I'd do the following. give both servers a static non changing IP: ldapA.yourdomain.tld, e.g. 10.0.0.1 on eth0 ldapB.yourdomain.tld, e.g. 10.0.0.2 on eth0 These two IPs will always be the same. You can access ldapA or ldapB anytime via it's designated name. For failover, use an alias: ldap.yourdomain.tld, e.g. 10.0.0.3 on eth0:0 on the active node Don't tell heartbeat of openldap and everything should be good.
