Method 1:
If u intend to assign user "scmen" to help root to change user's password using only 'passwd' command, then follow dbase77 and nawlej suggestion (which is using sudo). You may download the sudo program from :
To learn how to use sudo, pls refer to the same website for its documentation.
Method 2:
If the "scmen" user is also allowed to assist root to manage some adminstrative tasks, then you can assign "scmen" to belong to this group called sysadmin (GID=14) -- as suggested by bifitzmai. Once scmen belonged to sysadmin, then he/she is allowed to help other user to change password.
How to assign "scmen" to sysadmin?
Log in as root and do the following:
# usermod -G 14 scmen
Then from now on, scmen is allowed to use admintool to assist root to perform some administrative tasks. So if scmen needs to change password for user1 using admintool:
1. Login as scmen and starts admintool:
$ admintool &
2. Select user1 from the admintool-user window using yr mouse and then choose Edit-Modify menu.
3. NOw you should be able to see Modify-User window, so you may change the user password from Password Type, select Normal Password.
4. Then, click OK.
NOTE: Please be reminded that once scmen belonged to sysadmin group, he/she would be able to perform other adminstrative tasks like modifying user accounts, groups accounts, printers, softwares, hostnames, and serial ports. However, scmen can only do all these tasks by using admintool utility, but not through command-line (cannot use useradd, usermod or userdel).If you do not intend to allow scmen to do this, the best is to use sudo program.
And pls DO NOT duplicate another root account by changing yr scmen's UID into 0. (Observe column 3 for UID)
Eg:
# vi /etc/passwd
scmen:x:0:14::/export/home/user1:/bin/ksh
If you do the above step, it means now scmen has exactly the same amount of privileges like root. Do you want yr user scmen to be able to change everything in yr system without consulting root first (ie. shutdown system, delete system files)?
