It seems that there is one more entry on the master
but the two ldif files are absolutely identical.
Are you positive? Take a md5 of the two ldif, for instance? (They're
different filenames, if nothing else!)
I suppose there's a chance that differing config files could make the
numbers different, but I'm not sure. The hex values aren't all that easy
to come to a conclusion from (perhaps if you use -v and diff the output
you can see a human-readable dn that's different).
