I'm sure there are many ways to fix this, by in my pre-coffee state I can 
think of two.

1) NAT the traffic on the FW so that responses are sure to go to the right
   place.

2) Set the LDAP cluster with limited routing table, a /29 for example, so
   the traffic has to route through the firewall to get back to the rest
   of your network.

Q: Why do you have source, dest and firewall on same segment?
Q: Maybe dns round robin would be better for load balancing
