Hello Frank,

thanks for taking care of the bug.
The title should say [UBUNTU 20.04] - I can't seem to change that in Launchpad.
Boris should be back next week to take care of anything I missed.

Title:
  [UBUNTU 22.04] check_hostkeydoc is checking the certificate issuer too
  strictly (s390-tools)

Status in Ubuntu on IBM z Systems:
  New
Status in s390-tools package in Ubuntu:
  New

Bug description:
  == Comment: #0 - Viktor Mihajlovski <MIHAJLOV at de.ibm.com> - 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.
