If you want it to persist through password changes then script it and put it in roots crontab with all users that you want to not be required to change their passwords. Something like this. As far as i know there is no other way to do it, but i may be wrong.
I have a script running as a cron job in machine A . This script ftps some files everyday from machine A to machine B, and mails me about the status. It works fine for some days....and suddenly stops running. By viewing the log files, I see that the script itself was not invoked by cron on those... (4 Replies)
I could not find an entry for my linux user account in /etc/passwd file. I can remember some time back one of my SA showed the entry line using some other command. Can someone please help me on this to view the details of my linux user account? (3 Replies)
i wonder if there is a tool to read the /etc/passwd or /etc/shadow files in order to reset user accounts to the same one.
By moving (restore) all filessytem and data to another same Sun box, none of the users are able to logon to the new box which i didn't change nothing. But if i reset the user... (1 Reply)
I'm trying to make this work, and it half works. Accounts with password hashes matching the old crypt(3) algorithm work just fine:

hi, all
I just started on new box where I have to diff passwd working perfectly on the very same account/user. I see that shadow was added recently (I'm not a root in there), I see 'x' in passwd. Not sure how it should work, should I change old passwd for one defined in shadow? Or it's fine to... (20 Replies)
Hi all..
I moved the /etc/shadow and /etc/shadow files to /tmp and then rebooted my PARC machine running 5.10. I did it to see if I could recover from single user mode.
But, I forgot to enable the abort key-sequence which I earlier disabled.
Stuck!

Hi,
I have a Solaris 10 box where password aging is not functioning properly. Using the passwd command with the -l or -u options causes the lastchg field in the /etc/shadow file to be modified. Therefore, if a user's password is set to expire in 90 days and they are 1 day away, all they have... (4 Replies)

chpasswd(8) System Manager's Manual chpasswd(8)NAME
chpasswd - change user passwords in batch
SYNOPSIS
chpasswd [-D binddn] [-P path] [-c des|md5|blowfish | -e] [file]
DESCRIPTION
chpasswd changes passwords for user accounts in batch. It reads a list of login and password pairs from standard input or a file and uses
this information to update the passwords of this user accounts. The named account must exist and the password age will be updated. Each
input line is of the format:
user_name:password
If the hash algorithmus is not given on the commandline, the value of GROUP_CRYPT or, if not specified, CRYPT from /etc/default/passwd is
used as hash algorithmus. If not configured, the traditinal des algorithmus is used.
OPTIONS -c des|md5|blowfish
This option specifies the hash algorithmus, which should be used to encrypt the passwords.
-e The passwords are expected to be in encrypted form. Normally the passwords are expected to be cleartext.
-D, --binddn binddn
Use the Distinguished Name binddn to bind to the LDAP directory. The user will be prompted for a password for simple authentica-
tion.
-P, --path path
The passwd and shadow files are located below the specified directory path. chpasswd will use this files, not /etc/passwd and
/etc/shadow.
FILES
/etc/default/passwd - default values for password hash
