NAME

6       lppasswd - add, change, or delete digest passwords.
7

SYNOPSIS

9       lppasswd [ username ]
10       lppasswd -a [ -g groupname ] username
11       lppasswd -x username
12

DESCRIPTION

14       lppasswd  adds,  changes, or deletes passwords in the CUPS digest pass‐
15       word file, passwd.md5. When run by a normal user, lppasswd will  prompt
16       for  the  old  and new passwords.  When run by the super-user, lppasswd
17       can add new accounts (-a username),  change  existing  accounts  (user‐
18       name),  or  delete  accounts (-x username) in the digest password file.
19       Digest usernames do not have to match local UNIX usernames.

OPTIONS

22       lppasswd supports the following options:
23
24       -g groupname
25            Specifies a group other than the default system group.
26

SECURITY ISSUES

28       By default, the lppasswd program is not  installed  to  allow  ordinary
29       users  to  change their passwords. To enable this, the lppasswd command
30       must be made setuid to root with the command:
31       chmod u+s lppasswd
32
33       While every attempt has been  made  to  make  lppasswd  secure  against
34       exploits  that could grant super-user privileges to unprivileged users,
35       paranoid system administrators may wish  to  use  Basic  authentication
36       with accounts managed by PAM instead.
