Just a quick follow-up: I solved our problem. Something had changed the 
DC object in the Domain Controllers OU, causing the mismatch. I restored 
that object from a recent backup using ldbedit, and now everything is 
working again.

The most likely candidate for the root cause seems to be the recent 
FreeNAS install, which, as I heard, failed. Maybe something did get 
mixed up there at first.
