I came across this phrase in the link belowhttp://brandonhutchinson.com/wiki/Solaris_Password_Policy/usr/bin/passwd is used to modify password aging on existing accounts.  passwd does not update the last password change field (field 3) in /etc/shadow, so passwords could expire immediately after running it.What has the 3rd field in /etc/shadow got to do with the expiry of password?  I tried to force expire a user account and the 3rd field did change.sghk1> cat /etc/shadow | grep testtest:$1$khA8kfQ7$B1lHXn5N8h5CvKx0WnibV.:16665:7:420::::sghk1> passwd -f testpasswd: password information changed for testsghk1> passwd -s testtest      PS    00/00/00     7   420sghk1> cat /etc/shadow | grep testtest:$1$khA8kfQ7$B1lHXn5N8h5CvKx0WnibV.:0:7:420::::From 16665 to 0.So what does the author mean?Also, for existing users, how do we make policies/configurations in /etc/default/passwd take place on existing accounts?
