LDAP admin and basic structure setup requires running slapd. Move this
to first-run so we don't have to start slapd during setup. This should
avoid issues when running setup in a chroot.
Preseeding settings with debconf won't have any effect if the packages
are already installed. Instead, provide an override database to
dpkg-reconfigure.
- Break down setup process into methods.
- Make sure that LDAP entity setup is idempotent.
- Peform all entry updates while slapd is running instead of using
slapadd.
- Start slapd only when necessary. Shutdown (only) if we have started
slapd.
