SAP Sybase IQ uses a configuration object called LDAP server to allow LDAP user authentication.
Despite its name, the LDAP server is a configuration object that resides on the SAP Sybase IQ server, rather than an actual server. Its sole function is to provide a connection to a physical LDAP server to allow LDAP user authentication. Any configuration of the LDAP server configuration object applies only to the SAP Sybase IQ side of the LDAP user authentication equation. LDAP server configuration object configuration settings are never written to the physical LDAP server.
