Public bug reported: == Comment: #0 - Viktor Mihajlovski <[email protected]> - 2022-04-07 09:16:49 == The s390-tools script check_hostkeydoc can be used to perform the verification of the chain of trust for Secure Execution host key documents. The certificate verification is however too strict and doesn't match the checking performed by genprotimg. Affected is the OU field in the issuer DN of the host key document. As a consequence, verification failures will occur for host key documents issued for newer hardware generations like IBM z16.
