- Fix for original remediation which removed the `nullok` keyword and everything after it - Modification of STIG rule to include removing nullok also from /etc/pam.d/common-auth Rationale for modifying UBTU-20-010463: - /etc/pam.d/common-password does not contain nullok by default, nor does the keyword have any effect on changing passwords with `passwd` (empty passwords are not allowed with or without nullok keyword) - /etc/pam.d/common-auth contains nullok by default and thus allows logins to accounts with empty passwords DISA was notified of the issue. Some concerns were raised regarding effect on multifactor authentication, however, it was shown to work regardless of nullok keyword being present in /etc/pam.d/common-auth:pam_unix.so or not.
