Check Text ( C-29753r488321_chk )
Check the max days field (the 5th field) of /etc/shadow. # awk -F: '{print $1 ":" $5;}' /etc/shadow If the max days field is equal to 0 or greater than 60 for any account that is not password-locked, this is a finding.

Fix Text (F-29741r488322_fix)
Set the max days field to 60 for all user accounts. # passwd -x 60 Set the MAXWEEKS parameter in /etc/default/passwd to a positive, non-zero value of 8 or less.
