  28 <i>lppasswd</i> adds, changes, or deletes passwords in the CUPS
  29 digest password file, <i>passwd.md5</i>. When run by a normal
  30 user, <i>lppasswd</i> will prompt for the old and new passwords.
  31 When run by the super-user, <i>lppasswd</i> can add new accounts
  32 (<i>-a username</i>), change existing accounts (<i>username</i>),
  33 or delete accounts (<i>-x username</i>) in the digest password
  34 file. Digest usernames do not have to match local UNIX usernames.
  35 <h2 class="title"><a name="OPTIONS">Options</a></h2>
  36 <i>lppasswd</i> supports the following options:
  37 <dl>
  38 <dt>-g groupname
  39 </dt>
  40 <dd></dd>
  41 <dd>Specifies a group other than the default system group.
  42 </dd>
  43 </dl>
  44 <h2 class="title"><a name="SECURITY_ISSUES">Security Issues</a></h2>
  45 By default, the <i>lppasswd</i> program is not installed to allow ordinary
  46 users to change their passwords. To enable this, the <i>lppasswd</i> command
  47 must be made setuid to root with the command:
  48 <br>
  49 <pre>
  50 chmod u+s lppasswd
  51 </pre>
  52 <p>While every attempt has been made to make <i>lppasswd</i> secure against
  53 exploits that could grant super-user privileges to unprivileged users,
  54 paranoid system administrators may wish to use Basic authentication with
  55 accounts managed by PAM instead.
