You will hear the same thing from the OpenLDAP Community and will be 
asked to first verify the issue on the latest OpenLDAP with OpenSSL (no 
NSS). Even the latest RHEL7/CentOS7 OpenLDAP packages are behind and 
lack a lot of important bugfixes. If you use (are going to use) MDB 
(highly recommended) or replication then you'll definitely need to use 
the latest OpenLDAP version (with OpenSSL, no NSS).

The OpenLDAP Community usually recommends the free OpenLDAP RPM packages 
built with OpenSSL from http://ltb-project.org or to get supported 
packages from http://www.symas.com also built with OpenSSL.
