ldif_back_add: err: 68 text: send_ldap_result: conn=-1 op=0 p=0 slaptest: bad configuration directory!
error code 68 means entry already exists. It may simply be that slaptest isn't working correctly with the config db. You could of course try -d -1 to get better logging results rather than -d 1.
I would also note that you are using a rather old version of OpenLDAP with numerous known bugs. I would strongly advise you to build a more recent version.
