This is running on Scientific Linux 6 with the following packages: openldap-2.4.23-32.el6_4.x86_64 openldap-clients-2.4.23-32.el6_4.x86_64 openldap-servers-2.4.23-32.el6_4.x86_64
I would strongly advise you to use a current release of OpenLDAP linked to a current release of OpenSSL. The above packages are years out of date, and there are numerous known bugs with MMR fixed since then.
