RE: Problem importing LDIF file
I've been using ldapadd, but I can certainly give slapadd a try. However, I
realized that even if I can get the LDIF file to import, how would I make
sure that deleted users are removed from the OpenLDAP database? They
wouldn't be present in the new LDIF files (the ones generated after the user
is deleted), but they would still be present in the OpenLDAP database from
before they were deleted in AD.

Are you using ldapadd or slapadd? Note that slapadd is preferred if you
are starting the database from scratch. I also suggest reading up on the
"-c" option (continue on error) which will skip over the problem of entries
already existing (but also any other data issues).
