Specifies the host name and port number of a secondary Active Directory server available to the Federation Manager platform. If the primary Active Directory server does not respond to a request for authentication, this server would then be contacted. If the primary server is up, Federation Manager will switch back to the primary server. The format is also hostname:port. Multiple entries must be prefixed by the local server name.
When authenticating users from a data store that is remote, it is important that both the Primary and Secondary LDAP Server Ports have values. The value for one data store location can be used for both fields.
