Require MEIG to perform certificate matching on unique values

In a scenario where multiple CA certificates having the same value for the DN Subject parameter exist in the database, MEIG can retrieve the wrong CA certificate and cause a valid Trading Partner certificate to incorrectly be interpreted as invalid due to errors relating to an empty trustAnchors parameter.


There are 2 scenarios where this issue might be encountered:

1) The one we observed where Entrust are using 2 different root CAs with same DN to issue EV vs non-EV certs.

Refer to https://www.entrust.com/resources/certificate-solutions/tools/root-certificate-downloads

2) During CA renewal - the CA might reissue their new CA cert with same DN in say June - you might have one trading partner with a cert from May, one from July, and it won't work


It appears to be a design flaw in MEIG's certificate matching logic to rely solely on DN which may not be unique, and also not iterate through all available matching DN's. A more reliable design would be to match against authority key identifier and subject key identifier,

and/or iterate through all DNs that match.

What is your industry? Government
How will this idea be used?

As a vendor with a certificate that has a DN Subject matching another vendor's certificate DN Subject, I need my certificate to be recognised and allow me to transact with this government agency

    This issue has also been encountered during a certificate change in our ebMS/AS4 gateway and necessitated a creative approach and significant on call support effort and cost to investigate, understand and fix resultant messaging issues caused by the current certificate management implementation
