Creating a "big" database... large LDIF file. automated procedure?

Hi again. Thanks again for your responses to my prior posts.

So far, all of my experience with OpenLDAP has been with databases with a minimal number of entries... 200 at the most. I'd like to do some performance experiments with a much larger database, say 10,000 database entries or so. What would you recommend for creating such a database? (Entries don't have to have real, sensible data... maybe the distinguished name is an integer that increases by 1?) Is there an automated way for creating such a database?

Thanks,
