Yes, please do. The easiest way to do this is to connect with:

	ldapsearch ${auth_options} ${search_options} -E \!sync=rp 

This should pause after printing the search results and
"SyncInfo Received". When you delete a DN which matches
the search, you should see something like:

  dn: ...
  control: 1.3.6.1.4.1.4203.1.9.1.2 false MEsKAQMEENvalhY+vhAxkhS55kGsVLgENHJpZD

Also, if possible, please upgrade OpenLDAP. They've fixed
a lot of syncprov bugs since 2.4.26. I just did a quick
and successful retest of this scenario with 2.4.31.
