Password Expiration on 5.2

Admins,

I am trying to setup all user to have their password expire every 30
days. I have made two changes in "smit passwdattrs" and they are below.
I want to make sure that the system will expire a user's password every
month (30 days) and it will warn them 3 days before it is going to
expire. Would the below changes be correct? Looks like the default
Weeks between Expiration was -1. Any help would be appreciated.



Days to WARN USER before password expires [3]

Weeks between password EXPIRATION and LOCKOUT [4]

Thanks Larry
