The LDAP failover mechanism in Communications Express balances load between a number of configured master and slave LDAP servers. This increasing performance by decreases the response time. Communications Express contains an LDAP failover Manager module that is responsible to retrieve connections from the master or slave servers. Each load balancing server maintains a pool of available free connections. Whenever a Communications Express component requires a connection to the LDAP server, the LDAP failover manager provides the component with a connection based on the load balancing strategy employed.
