Okay ;-)
0) sudo -s
1) /etc/init.d/slapd stop
2) cd /var/lib/ldap
3) rm *
4) slapadd -l /root/bin/old/dc\=intern\,dc\=domain\,dc\=de.ldif
5) chown openldap\: *
6) /etc/init.d/slapd start
This is how I restored the backup to my test box and how I did it this
weekend on the productive box where the error still exists. I also removed
the DB_CONFIG, but after the restore the DB_CONFIG has the same entries.
