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.

htdigest - manage user files for digest authentication
SYNOPSIS
htdigest [ -c ] passwdfile realm username
SUMMARY
htdigest is used to create and update the flat-files used to store usernames, realm and password for digest authentication of HTTP users.
Resources available from the Apache HTTP server can be restricted to just the users listed in the files created by htdigest.
This manual page only lists the command line arguments. For details of the directives necessary to configure digest authentication in httpd
see the Apache manual, which is part of the Apache distribution or can be found at http://httpd.apache.org/.
OPTIONS -c Create the passwdfile. If passwdfile already exists, it is deleted first.
passwdfile
Name of the file to contain the username, realm and password. If -c is given, this file is created if it does not already exist, or
deleted and recreated if it does exist.
realm The realm name to which the user name belongs.
username
The user name to create or update in passwdfile. If username does not exist is this file, an entry is added. If it does exist, the
password is changed.
SECURITY CONSIDERATIONS
This program is not safe as a setuid executable. Do not make it setuid.

My scenario is as follows:

We are real strict when it comes to passwords. Every 60 days the admins have to change passwords on all of the accounts. And there is pretty strict enforcement of the type of passwords chosen. This is a tedious and monotonous job. Ww don't use NIS or LDAP, so this has to be done on each machine. ... (5 Replies)
I've been using various versions of UNIX and Linux since 1993, and I've never run across one that showed your password as you type it in when you log in, or one that stored passwords in plain text rather than encrypted. I'm writing a script for work for a security audit, and two of the... (5 Replies)
