LDAP servers sit behind Load Balancers.
Primary and Secondary LDAP servers are defined as Load Balancer VIPs.
ACS not failing over to secondary LDAP server (VIP) ???
When disabling connection to primary LDAP servers, still able to make connection on port 636 from ACS to Load Balancer.
Just like to confirm how ACS checks LDAP health so I can confirm whether ACS or load balancer issue.
