<h2 class="title"><a name="NAME">Name</a></h2>
lppasswd - add, change, or delete digest passwords.
<h2 class="title"><a name="SYNOPSIS">Synopsis</a></h2>
<b>lppasswd
</b>[
<i>username
</i>]
<br>
<b>lppasswd
</b>-a [ -g
<i>groupname
</i>]
<i>username
</i><br>
<b>lppasswd
</b>-x
<i>username
</i><h2 class="title"><a name="DESCRIPTION">Description</a></h2>
<i>lppasswd</i> adds, changes, or deletes passwords in the CUPS
digest password file, <i>passwd.md5</i>. 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.
