I'll tell you what I do, but it is a little risky. First I add the users to a "prototype" box. This is just some box where I start. I add the users, assign initial passwords, and I ask the user to sign on, change their passwords, and be sure that they like the shell, gcos info etc. I do not want to copy this around and then find that they csh or something. After the users accounts are all ready on the prototype box, I extract their lines from /etc/password and /etc/shadow. I use this to create a simple script that appends the lines to /etc/passwd and /etc/shadow. The script also makes the home directories, etc. I test this script on a test system. Once I am sure that I trust the script, I use an automated procedure to transfer to the boxes in question and run it. Like I said, this is a little risky. But I am careful and I am confident that I can correct any fumbles that occur.

lppasswd

lppasswd(1)							    Apple Inc.							       lppasswd(1)

NAME

       lppasswd - add, change, or delete digest passwords.

SYNOPSIS

       lppasswd [ username ]
       lppasswd -a [ -g groupname ] username
       lppasswd -x username

DESCRIPTION

       lppasswd  adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt
       for the old and new passwords.  When run by the super-user, lppasswd can add new accounts (-a username), change	existing  accounts  (user-
       name), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames.

OPTIONS

       lppasswd supports the following options:

       -g groupname
	    Specifies a group other than the default system group.

SECURITY ISSUES

       By  default,  the lppasswd program is not installed to allow ordinary users to change their passwords. To enable this, the lppasswd command
       must be made setuid to root with the command:
       chmod u+s lppasswd

       While every attempt has been made to make lppasswd secure against exploits that could grant super-user privileges  to  unprivileged  users,
       paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead.
