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.
