Add your basedn to basedn (eg: `echo o=denkn,c=at > basedn`).
For initialization, first shutdown slapd and delete `/var/lib/ldap/` (you will lost all your data!),
then use `./90.root.ldif | slapadd -b `cat basedn` -v`.
Now you can start slapd again.
Via `ldapadd -Y external` you can add any other ldif.
For adding user run `./90.user.ldif.sh | ldapadd -Y external`.
