Details
Check Text (C-271634r1091614_chk)
Verify that OL 9 does not allow null passwords with the following command:
$ grep -i nullok /etc/pam.d/system-auth /etc/pam.d/password-auth
If output is produced, this is a finding.
Fix Text (F-75591r1091613_fix)
Remove any instances of the "nullok" option in the "/etc/pam.d/password-auth" and "/etc/pam.d/system-auth" files to prevent logons with empty passwords.
Note: Manual changes to the listed file may be overwritten by the "authselect" program.
