For others you want rightid=%fromcert so it matches all valid
certificates. Or rightid="CN=*,O=IKEv2 VPN"

Note: ALL fields in certificate subject must be present in
configuration for it to match at all. So if you have
rightid="CN=*,O=IKEv2 VPN" and certificate has "CN=testclient" this
can't match. Or other way around if certificate has more fields it
doesn't match either.

Also note you need one certificate per road warrior. So same
certificate can't be used on multiple road warriors (some call these
clients but in IPsec terminology is different).
