To avoid heavy load or to distribute load on the LDAP server, we recommended that you configure multiple connections to the user source and ensure that there is one unique LDAP connection for each Primary Server or authentication Satellite Server. LDAP connections configured for the Primary Server should always be based on which server is closer in terms of connectivity. This will prevent the same LDAP server from being loaded from all Primary Servers and Authentication Satellites. To ensure fault tolerance when the LDAP server is down, it is always better to have multiple connections available and configured for the Primary Server. It is important to order the connections in such a way that different servers have a different LDAP connection specified as the first connection.
