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.
