Check Text (C-260570r1082233_chk)
Verify that null passwords cannot be used. Run the following command:
$ grep nullok /etc/pam.d/common-auth /etc/pam.d/common-password
If this produces any output, this is a finding.
Fix Text (F-64207r1082232_fix)
Remove any instances of the "nullok" option in "/etc/pam.d/common-password" to prevent logons with empty passwords.
Remove any instances of the "nullok" option in "/etc/pam.d/common-auth" and "/etc/pam.d/common-password".
