Controlling User Passwords
Once you have created a user account, you can control the user s access to it The passwd tool lets you lock and unlock a user's account You use the passwd command with the -l option to lock an account, invalidating its password, and you use the -u option to unlock it You can also force a user to change his or her password at given intervals by setting an expiration date for that password The chage command let you specify an expiration limit for a user s password A user can be required to change his or her password every month, every week, or at a given date Once the password expires, the user is prompted to enter a new one You can issue a warning beforehand, telling the user how much time is left before the password expires If there is an account that you want to close, you can permanently expire a password You can even shut down accounts that are inactive too long In the next example, the password for the chris account will stay valid for only seven days The -M option with the number of days sets the maximum time that a password can be valid
chage -M 7 chris
To set a particular date for the account to expire, use the -E option with the date specified mm/dd/yyyy
chage -E 07/30/2003 chris
To find out what the current expiration settings are for a given account, use the -l option
chage -l chris
You can also combine your options into one command
chage -M 7 -E 07/30/2003 chris
A listing of the chage options appears in Table 28-2
