    scanner.</desc>

  <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>
    <item xmlns="http://projectmallard.org/1.0/" xmlns:its="http://www.w3.org/2005/11/its" xml:id="dconf-profile-user">
    <p>Create the <file its:translate="no">user</file> profile which contains
    the following lines:</p>
    <listing its:translate="no">
      <title><file>/etc/dconf/profile/user</file></title>
      <code>user-db:user
system-db:local</code>
    </listing>
    <p><input its:translate="no">local</input> is the name of a
    <sys its:translate="no" xref="dconf">dconf</sys> database.</p>
  </item>
    <item xmlns="http://projectmallard.org/1.0/" xml:id="dconf-profile-user-dir">
    <p>Create the directory <file>/etc/dconf/db/local.d/</file>
    if it does not already exist.</p>
  </item>
    <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>
    <item xmlns="http://projectmallard.org/1.0/" xml:id="dconf-update">
    <p>Update the system databases:</p>
    <screen><output style="prompt"># </output><input>dconf update</input></screen>
  </item>
    <item xmlns="http://projectmallard.org/1.0/" xml:id="dconf-logoutin">
    <p>Users must log out and back in again before the system-wide
    settings take effect.</p>
  </item>
  </steps>
