Hi,
As a follow-up from https://bugs.openldap.org/show_bug.cgi?id=10373, it appears
that the configuration I had shared can be converted to olc with slaptest,
however does not pass validation be loaded when the daemon start:
```
$ slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d
$ slaptest -u -F /etc/openldap/slapd.d -d stats -d pcache
