Data persistence
----------------
The image exposes the directory, where the data is written
(`VOLUME ["/var/lib/ldap"`). Please make sure that
these directories are saved (in a data-only container or alike) in order to make
sure that everything is restored after a new restart of the application.
The image exposes one directory (`VOLUME ["/var/lib/ldap"]`). It both holds the
database and the configuration (which is symlinked in a pretty hacky way - see
the `entrypoint.sh` file if interested). Please make sure that this directory is
saved (in a data-only container or alike) in order to make sure that everything
is restored after a new restart of the container.
