How do you currently back up your LDAP database?? You could use

Code:

slapcat -v -l backup.ldif

..to back up your current openLDAP database to a file. Then you could import it:

Code:

/etc/init.d/slapd stop ...stop LDAP first

slapadd -l backup.ldif  ..will add the backed-up data to your LDAP database

chown -R openldap:openldap /var/lib/ldap/* ..fix permissions if needed

As long as you take good backups first, you should just be able to add the existing data in, as far as I know. Be sure to TEST this first on your backup/lab system, before doing it in production.
