Thanks.
From RFC 6125:
6.4.4. Checking of Common Names
As noted, a client MUST NOT seek a match for a reference identifier of CN-ID if the presented identifiers include a DNS-ID, SRV-ID, URI-ID, or any application-specific identifier types supported by the client.
Therefore, as I noted, the certcn is immaterial since I have a DNS: value specified, and it is then required that the certcn be ignored. The rest of the RFC doesn't really cover special cases like localhost. I still see nothing in the RFC that states what's I'm doing is invalid. It does appear to be outside of what's normally done, but that's not surprising.
RFC 6761 specifically notes that "localhost." is in fact a domain name (Section 6.3). Therefore, my certificates are in fact correct, and the OpenLDAP code check is indeed a bug.
