    <desc>Prevent the user from being able to log in using a fingerprint
    scanner.</desc>
  </info>

  <title>Disallow login using a fingerprint</title>

  <p>Users with a fingerprint scanner can use their fingerprints
  instead of a password to log in. Fingerprint login
  <link href="help:gnome-help#session-fingerprint">needs to be set up by the
  user</link> before it can be used.</p>

  <p>Fingerprint readers are not always reliable, so you may wish to disable
  login using the reader for security reasons.</p>

  <steps>
    <title>Disable login using a fingerprint reader:</title>
    <include xmlns="http://www.w3.org/2001/XInclude" href="dconf-snippets.xml" xpointer="xpointer(/*/*[@xml:id='dconf-profile-user'])"/>
    <include xmlns="http://www.w3.org/2001/XInclude" href="dconf-snippets.xml" xpointer="xpointer(/*/*[@xml:id='dconf-profile-user-dir'])"/>
    <item>
      <p>Create the key file
      <file>/etc/dconf/db/local.d/00-login</file> to provide
      information for the <sys>local</sys> database.</p>
      <listing>
        <title><file>/etc/dconf/db/local.d/00-login</file></title>
<code>
# Specify the dconf path
[org/gnome/login-screen]

# Disable fingerprint reader
enable-fingerprint-authentication=false
</code>
      </listing>
    </item>
    <item>
      <p>To prevent the user from overriding these settings, create the file
      <file>/etc/dconf/db/local.d/locks/login</file> with the following
      content:</p>
      <listing>
        <title><file>/etc/dconf/db/local.d/locks/fingerprintreader</file></title>
<code>
# List the keys used to configure login
/org/gnome/login-screen/enable-fingerprint-authentication
</code>
      </listing>
    </item>
    <include xmlns="http://www.w3.org/2001/XInclude" href="dconf-snippets.xml" xpointer="xpointer(/*/*[@xml:id='dconf-update'])"/>
    <include xmlns="http://www.w3.org/2001/XInclude" href="dconf-snippets.xml" xpointer="xpointer(/*/*[@xml:id='dconf-logoutin'])"/>
  </steps>
