When run by a normal user, <i>lppasswd</i> will prompt for the old and new passwords. When run by the super-user, <i>lppasswd</i> can add new accounts (<i>-a username</i>), change existing accounts (<i>username</i>), or delete accounts (<i>-x username</i>) in the digest password file. Digest usernames do not have to match local UNIX usernames. <h2 class="title"><a name="OPTIONS">Options</a></h2> <i>lppasswd</i> supports the following options: <dl> <dt>-g groupname </dt> <dd></dd> <dd>Specifies a group other than the default system group. </dd> </dl> <h2 class="title"><a name="SECURITY_ISSUES">Security Issues</a></h2> By default, the <i>lppasswd</i> program is not installed to allow ordinary users to change their passwords. To enable this, the <i>lppasswd</i> command must be made setuid to root with the command: <br> <pre> chmod u+s lppasswd </pre> <p>While every attempt has been made to make <i>lppasswd</i> 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. <h2 class="title"><a name="SEE_ALSO">See Also</a></h2> <a href='man-lp.html?TOPIC=Man+Pages'>lp(1)</a>, <a href='man-lpr.html?TOPIC=Man+Pages'>lpr(1)</a>, <br> <a href='http://localhost:631/help'>http://localhost:631/help</a> <h2 class="title"><a name="COPYRIGHT">Copyright</a></h2> Copyright 2007-2013 by Apple Inc. </body> </html>
