Does this actually work with OpenSSL and v3 CA certs that have "X509v3<br>
Authority Key Identifier" extensions? With these extensions present<br>
(default when OpenSSL constructs CA certs, ...), certs whose serial number<br>
does not match the "serial" field in the extension are not considered<br>
to be root CA certs (not self-signed), and CA certs sharing the same<br>
keys and DN, but carrying different serials, simply don't match.<br>
<br>
If I roll-back the serial numbers and issue a cert with all the details<br>
(including serial number, ...) the same, but just the start/end dates<br>
changed to start before the expiration of the verifier's expired CA,<br>
and end after today's date, the verifier ends up with a trust chain that<br>
starts with the expired cert and fails, regardless of whether the server<br>
sends the new root CA cert or not.<br>

A client with CAfile containing just "CA0.pem" fails to verify
a server<br>
configured to send the SRV,CA1 trust chain. My verification callback is<br>
called three times and produces:<br>
<br>
Trace: certificate verification depth=1 verify=0 subject=<fixed-ca-dn><br>
Error: CA certificate verification failed for <peer> certificate
has expired<br>
<br>
Trace: certificate verification depth=1 verify=1 subject=<fixed-ca-dn><br>
<br>
Trace: certificate verification depth=0 verify=1 subject=<server-dn><br>
<br>
If the verifier trusts the "CA1.pem" cert, I see instead:<br>
<br>
Trace: certificate verification depth=1 verify=1 subject=<fixed-ca-dn><br>
<br>
Trace: certificate verification depth=0 verify=1 subject=<fixed-server-dn><br>
<br>
How does one construct a working (re-issued root CA) example with OpenSSL?<br>
Am I setting this up incorrectly, or does OpenSSL not in fact support<br>
establishing trust in re-issued root CA via now expired root CAs?<br>
<br>
I have not tried to do this without the "issuer key identifier"
extension,<br>
but don't really expect to find anything different...<br>
