@Zamfir: login.defs defines the defaults that are set up for a user on account creation. These defaults can be overridden by chage or passwd commands. To see what applies to a user, see
chage -l $user

Hi,

My question is the following:

if you have those set in login.defs, can they be overridden by chage command?
something like:

chage -W10 -m7 -M42

which will apply for this user? (/etc/login.defs or /etc/shadow – because chage modifies /etc/shadow in this example)

does this apply for Root account ? — Fri, 08 Oct 2010 12:06:56 +0000

My aduitor has asked me to change the value for this following 3:
PASS_MAX_DAYS 99999
PASS_MIN_DAYS 0
PASS_WARN_AGE 7

As i have only Root account on the machine and no other account are configured.
Also, i always took the console of the server. It’s configured in UI.

Thanks in Advance !!!

Thank you. I came across this article while searching for information on password expiry. Useful.

John,

This is for system password aka ssh login, if your email server using system password then same limit will apply

Is this for email passwords or system logins like cPanel or SSH?

Thanks
