dbenv_open(/var/lib/ldap). 521fd341 bdb(dc=luthresearch,dc=net): Program version 4.6 doesn't match environment version 4.7 521fd341 bdb_db_open: database "dc=luthresearch,dc=net" cannot be opened, err -30972. Restore from backup!
I already covered this with you. Your old openldap build used BDB 4.6. Your new OpenLDAP build uses BDB 4.7. You need to delete the ldap database on this server, slapcat the db on your other server, and slapadd that export into this server, or start over from scratch. I also noted why using /var/lib/ldap is likely not a wise idea for your db, as it conflicts with the system defaults.
