LDAP Server Failover

LDAP Server Failover

You can define multiple LDAP servers. When PowerExchange issues an LDAP authentication request, it connects to the first available LDAP server, based on the order in which the LDAP_HOST statements occur in the DBMOVER configuration file.
If a failed server returns to operation, it is used for subsequent LDAP user validation calls.
To define multiple LDAP servers, in the DBMOVER configuration file on the PowerExchange Listener or PowerExchange Logger for Linux, UNIX, and Windows machine, define an LDAP_HOST statement for each LDAP server.
PowerExchange supports a basic level of resilience to LDAP server failure by connecting to the first LDAP server for which a connection is available. However, this implementation does not provide resilience to LDAP server failures that do not manifest themselves as connection failures.
