How to force users to change their password

[Juerg DENNEBERG]

How can I force the users to change their password. I want all (about 600) to change their password when they log in the next time only. (HP UX 11.0) Do I have to use SAM and touch every user? I do not hope. Can I exclude certain users from being forced?

See the section on password aging in man (4) passwd.

You will need to write a script to extract all users then on those users that you wish to force a new password simply issue a passwd -f username command. Man passwd for details.

Ouch, I hope you are taking tomorrow off or having your phone disconnected.

You could script it.

If you have password againg policy enabled, then you can do this automatically by setting the agings.

In your case, if you want only for specific users, then add a 'passwd' check line in the profiles or in a common profile.

# man passwd

You are in luck, I had a script that was extremely close. It also has an array that you can set to exclude those users that you wish to 'skip' over. If you are using NIS then change the cat /etc/passwd to ypcat passwd, I would also comment out the actual passwd -f ... command until you are satisfied with the results.

Attached is agepasswds.sh.

Quick script to do it for all users with UID 100 or greater:

#!/usr/bin/sh

for i in `awk -F: '{if($3>=100){print $1}}' /etc/passwd`
do
passwd -f $i
done

Hi Juerg,
You can do a work around also. Edit the
passwd file and add a ,.. in the passwd entry
of the users you have to force the passwd change. Take BACKUP of passwd before changes.
This will force the users to change the passwd
next time.
