Hi Quanah, It’s not a replication setup. The consumer is a relatively ancient proprietary implementation of the syncrepl protocol, over which I have very influence.
I believe the problem is syncprov.c lines 3335 and 3341, which appear to be setting `do_present = SS_PRESENT;` while simultaneously ignoring the value of si->si_nopres. Replacing the lines above with `if ( !si->si_nopres ) do_present = SS_PRESENT;` appears to fix the problem for my use case, and is closer to how the logic worked in previous versions of slapd. Thanks!

The *only* time no-present should be set to TRUE is when it's on top of an accesslog database that's being used by delta-syncrepl, as explicitly stated in the man page.
