Sybase provides failover support for the LDAP server. You can set up two LDAP URL search strings—one for the primary LDAP server and one for the secondary LDAP server—using sp_ldapadmin. If both URL search strings have been created, Adaptive Server uses the primary search string as long as that search string is valid and the primary LDAP server is active. Should the primary fail to respond, Adaptive Server uses the secondary URL search string.
