RHEL 5 update 4. How to force a user to change the password at his next logon.

Thanks in advance.

You can force a password to immediately expire with

Code:

chage -d 0 username

why I'm not works.
when we use option -d , user cannot login(rhel5.2, ssh4.3).

Did they ever have a password before? If not, you need to create one for them. This will not force their first password.

It have password, but still not works. ???

==================
# grep ratcha /etc/passwd /etc/shadow
/etc/passwd:ratcha.c:x:510:500:System Admin:/home/ratcha.c:/bin/ksh
/etc/shadow:ratcha.c:$1$O1z5V6.2$en8cRSXbDS0VGAT/XHbEZ/:14515:7:90:7:::
# passwd -d ratcha.c

Chage -d should work. Can you log in as that user on the console?

User can log in to server normally.
But I want to test force them to change password at first login.

Why option -d not work for me ???
