  16 .SH NAME
  17 lppasswd \- add, change, or delete digest passwords.
  18 .SH SYNOPSIS
  19 .B lppasswd
  20 [
  21 .I username
  22 ]
  23 .br
  24 .B lppasswd
  25 -a [ -g

  30 .B lppasswd
  31 -x
  32 .I username
  33 .SH DESCRIPTION
  34 \fIlppasswd\fR adds, changes, or deletes passwords in the CUPS
  35 digest password file, \fIpasswd.md5\fR. When run by a normal
  36 user, \fIlppasswd\fR will prompt for the old and new passwords.
  37 When run by the super-user, \fIlppasswd\fR can add new accounts
  38 (\fI-a username\fR), change existing accounts (\fIusername\fR),
  39 or delete accounts (\fI-x username\fR) in the digest password
  40 file. Digest usernames do not have to match local UNIX usernames.
  41 .SH OPTIONS
  42 \fIlppasswd\fR supports the following options:
  43 .TP 5
  44 -g groupname
  45 .br
  46 Specifies a group other than the default system group.
  47 .SH SECURITY ISSUES
  48 By default, the \fIlppasswd\fR program is not installed to allow ordinary
  49 users to change their passwords. To enable this, the \fIlppasswd\fR command
  50 must be made setuid to root with the command:
  51 .br
  52 .nf
  53 chmod u+s lppasswd
  54 .fi
  55 .PP
  56 While every attempt has been made to make \fIlppasswd\fR secure against
  57 exploits that could grant super-user privileges to unprivileged users,
  58 paranoid system administrators may wish to use Basic authentication with
  59 accounts managed by PAM instead.
