Hi Howard, unfortunately thereŽs no update for openladp under SL4, thatŽs why we are using such version. In fact I see no newer versions but for Fedora and Mandriva http://www.rpmfind.net/linux/rpm2html/search.php?query=openldap In fact, other sites are living nice with that version or older ones. In any case, I have compiled and built latest stable version from openldap project webpage (2.3.39) and I get the same problem. I'm not saying this is a bug from ldap, but something with local area network configuration. I'm asking for some support to debug this problem actually.
