I don't consider this appropriate.  If you ask not to automatically
configure slapd, then the package is not usable until manual action is taken
and we should not mark the package as "installed".

We should, however, ensure that removing the package does not fail when it's
unconfigured.  This is a policy violation in the init script, policy
requires the init script to return success when 'stop' is called for a
service that isn't running.
