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  user-
       name),  change  existing  accounts (username), or delete accounts (-x username) in the digest password file. Digest user-
       names 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.
