The attribute uniqueness overlay can cause syncrepl to jam up. Consider this case:

The obvious answer is for syncrepl to bypass all data checks, as the supplier server should have already enforced them. The problem with that is that clients could see data that breaks the rules if they query while syncrepl is running (unless the refresh phase is handled as a single transaction and thus isolated from clients until it is complete).

We've talked about doing this isolation in the first refresh upon slapd startup. That might still be a good idea.

Doing it on every refresh seems far more problematic, because without some type of multi-version concurrency control, that means making the server non-responsive until the refresh completes.
