I am in the process of migrating my OpenLdap 2.3 system to a new OpenLdap 2.4 system but something is not working right for the import(slapadd) to the new system. There are 35,895 objects defined in the LDIF generated by slapcat.
I would suggest you start with ldapadd to import, rather than slapadd, as you likely need the additional validation steps initially when doing the migration from 2.3 to 2.4.
I'd also avoid using RH's native packages and use a current release. The LTB project and Symas both provide free alternatives to RH's builds.
