AI Summary

The case involves a misissuance incident where KPN, a certificate authority under PKIoverheid, issued a certificate with an invalid organizationalUnitName. The CA became aware of the issue through a Bugzilla notification and took immediate action, including informing the affected customer and revoking the erroneous certificate. Affected certificates were confirmed to be limited to one, and KPN implemented regex validation on the OU field to prevent future occurrences. The CA also committed to enhancing its validation processes and introduced a post-issuance linting tool to further mitigate risks. The issue has been resolved, and the bug is now closed.
