I can add that if you're using subjectAltName extension and place
many DNS names into it, this will do the trick for the name-based
virtual hosts. In the presence of the subjectAltName with the DNS
entries in it, the DNS name of the server SHOULD (if memory servers
me right: I am not able to find the reference document now) be
checked against the subjectAltName components. At least
IE/Mozilla/Firefox/OpenLDAP/curl/elinks are doing these checks. It
is a bit different from the wildcard certificates, since no wildcards
are here, just the bunch of the dNSName objects in the subjectAltName.
