No. One or the other must match, but the CN must be an FQDN. The point
of alternatives is to support wildcards, aliases, and non-DNS name forms
(such as IP address).
RFC 6125 which in turn mentions RFC 4513.
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
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.
