Hi Quannah,
thanks for support. Now I understand little bit more ldif syntax/rules. Yes, the source code is option as well, but I tried to avoid it :)
I know there is slapd.conf to cn=config converter, but unfortunately I was not able to make it work (errors during conversion).
Thanks for help anyway. If I figure this out, I'll post result for future generations.
Best regards
Martin Stejskal
