+*** Fixed `LDAP_OPT_ON' libraries configuration.
+
+The original fix of local `configure.in' revision 1.19 (2004/12/19
+21:10:02 +0) introduced lossage on another class of systems. In some
+openldap versions `ldap_*' functions may link successfully without
+`-lber', but compiling and linking program with `LDAP_OPT_ON' may
+require `-lber'. When configuring ldap libraries, check for such
+systems, and in a cleaner way than in upstream.
