Camerfirma: Invalid authorityKeyIdentifier, violating Mozilla Policy and RFC 5280

RESOLVED FIXED AC Camerfirma, S.A.
AI Summary

Camerfirma was found to have issued certificates that violated the requirements of RFC 5280 and Mozilla Policy regarding the Authority Key Identifier. Specifically, approximately 3233 certificates included both a key identifier and an issuer name with serial number, which is prohibited. The CA acknowledged the misinterpretation of the policy and developed an action plan to rectify the issue, committing to issue certificates with only the key identifier moving forward. The problem was resolved, and all new certificates issued since late 2019 comply with the updated requirements.
