Wessel,
Just pass heartbeat an IP, not a service.
If you use IPaddr2 it will also send a gratuitous ARP that will cut down
the failover time.
eg.
primarynode.mycompany.com IPaddr2::10.10.10.50/24/eth0
All the services will stay running, if you want to do service checks to
watch slapd to see if it breaks you can use the "mon" project to kickoff
a heartbeat failover.
