Yep, since RH finally switched from gdbm to Berkeley DB as the 
database engine for ldbm.

1)If you're going to go to the effortof dumping and restoring your 
database, you might as weel get some real return for your effort. So, 
upgrade to openldap>=2.1.25 at least, and seriously consider using the bdb 
backend instead of the ldbm backend.
2)Use ldapadd -c -S reject.ldif, and then you can easily see which entries 
did not make it and why, and you can import the on their own (instead of 
the whole db for a few entries). The -S option is not available in 
openldap-clients-2.0.x.

(Note, I'm doing this on RHEL2.1 AS instead, as I couldn't get the 
performance I required out of 3.0).
