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 pass‐
       word 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.
