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)

yppasswd - change login password in Network Information System (NIS)
SYNOPSIS
[name]
Remarks
The Network Information Service (NIS) was formerly known as Yellow Pages (YP). The functionality remains the same; only the name has
changed.
DESCRIPTION
changes or installs a password associated with the login name in the Network Information System (NIS). The NIS password can be different
from the one on your own machine. If name is omitted, it defaults to the name returned by (see getlogin(3C)).
prompts for the old NIS password (even if it does not exist), then twice for the new one. The old password must be entered correctly for
the change to take effect. Checks occur to ensure that the new password meets the following construction requirements.
o Only the first eight characters are significant.
o A password can be as few as four characters long if it contains
o at least one special character or
o a mixture of numeric, uppercase and lowercase letters.
o A password can be as few as five characters long if it contains a mixture of
o uppercase and lowercase letters or
o numeric and either uppercase or lowercase letters.
o A password must contain at least six characters if it contains only monocase letters.
All these rules except the first are relaxed if you try three times to enter an unacceptable new password. You cannot, however, enter a
null password.
Only the owner of the name or the superuser can change a password.
The Network Information System password daemon, must be running on the master NIS password server to change NIS passwords. See yppass-
wdd(1M).
WARNINGS
The password update protocol passes the old and new passwords to the master NIS server at once. Thus, if the old NIS password is incor-
rect, no notification is given until the new NIS password is successfully entered.
The password construction rules are different from those of the HP-UX command (see passwd(1)).
The root user's password cannot be changed using or Therefore, root users must change their password in the files database and then recon-
struct the NIS maps using the command. For more information on how to use the command, see ypmake(1M).
