I run the following nightly from cron. Note that I have do run into situations
where the ldbmcat fails, even though the database seems otherwise OK - I have
not got round to tracking these down yet. My LDAP database is not fully in
production yet. I feel more comfortable with a text backup, which can be
fed back into ldif2ldbm to create the databases from scratch (in theory)
