When a major failure occurs in the LDAP directory server specified by the primary URL, and the server no longer responds to network requests, Adaptive Server attempts to connect to the secondary LDAP directory server specified by the secondary URL. Adaptive Server uses the LDAP function ldap_init to determine if it can open a connection to the LDAP directory server. A null or invalid primary URL string causes Adaptive Server to attempt to fail over to a secondary URL. Failures returned by LDAP bind or search operations do not cause Adaptive Server to fail over to the secondary URL.
