Actalis: two CAs with the same CRLDP
Actalis faced an issue where two different Certificate Authorities (CAs) were associated with the same CRL Distribution Point (CRLDP), which could lead to complications in certificate revocation. This problem arose after the removal of the Organizational Unit (OU) attribute during a certificate reissuance, resulting in a mismatch between the issuer and subject of the certificates. Actalis acknowledged the issue and took corrective actions, including revoking the problematic certificate and restoring the original subject attributes. The incident was resolved with no reported impact on end-user certificates or service disruptions.
- Reissued the 'AgID CA1' SubCA certificate, removing the OU attribute.
- Revoked the problematic 'AgID CA1' certificate and reissued it with the original OU attribute.
- All identified action items were addressed.
- Requested formal closure of the incident.
- Incident officially closed.
