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
       (username), 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.
