When LDAP_SERVER is enabled, all non-admin users authenticate using LDAP. The LDAP_LOCAL_PREFIX <prefix> keyword allows filtering certain users to use local c-tree authentication if their user name begins with <prefix>. This prefix comparison is case-insensitive.
Note: If the user account existed prior to this V12 change, local authentication may fail with LDRQ_ERR (985) or SQL error (-17985): CT - Logon is denied because this user account requires LDAP authentication, but c-tree Server has not enabled LDAP authentication. If this occurs, the user account will need to be deleted and re-created.
