Compiling 2.4.17 with OpenSSL was more succesful than on 2.4.11. I think that's a Debian issue. Anyway, I have my server up and running! Thanks a lot Dieter for answering all my questions. But I have a minor question left. Each time I restart slapd I have to enter the PEM pass phrase. Is there a way to remember or not prompt for the passphrase?
