    - SECURITY UPDATE: Unauthenticated domain controller compromise by
      subverting Netlogon cryptography (ZeroLogon)
      + debian/patches/zerologon-*.patch: backport upstream patches:
        + For compatibility reasons, allow specifying an insecure netlogon
          configuration per machine. See the following link for examples:
          https://www.samba.org/samba/security/CVE-2020-1472.html
        + Add additional server checks for the protocol attack in the
          client-specified challenge to provide some protection when
          'server schannel = no/auto' and avoid the false-positive results
          when running the proof-of-concept exploit.
