Password issue

shivan — Tue, 19 Dec 2006 06:47:46 GMT

We force reset password of user at login and when user login we see error below. Can someone help us on this issue.
# passwd -f xxxx
$ su - xxxx
Your password was changed by root
Password:
Last successful login for xxxx: Tue Dec 19 EST5EDT 2006
Last unsuccessful login for xxxx: Tue Dec 19 EST5EDT 2006
Your password has expired.
su: Password for xxxx has expired. Choose new password and try again
su: Sorry

Shivan,
this is the correct behaviour !
From "man passwd":
"-f Force user to change password upon next login by expiring the current password."

So you expire the pasword and then log on as that user and the password is signalled as expired.

hi,

to prevent this from occurring, you should not use the "-f" switch when issueing the passwd command. otherwise, it will ask from a password change when the user tries to login next time.

hope this helps!

kind regards

How do we fix this issue. We want user to change password on login.

This works very well on solaris. When we force change password of user (passwd -f xxxx), system prompts for old password and then choose new password on user xxxx login.

Hi,
the way to fix this is to log on again (without su).
So,as root:
passwd -f xxx

Now log on as the user for whom you changed the password and it will state that the password is expired and ask the user to change the password.

If you su - to the user the process does not work the way you want it to.

Hi,
This is not an issue, it works as it designed. You are handling it in a wrong way.

After executing passwd -f user, please set the new password for that user. This can be done either when you try to login using that user or run passwd command as root again to set the new password for that particular user.

unless, you set a password for that user, you cannot do a su, it will fail....

HTH,

Peter, thanks for the info. Password expiry works well but does not work when we do su.
