    <title>Jetty 9.x SAML Adapters</title>
    <para>
        Keycloak has a separate SAML adapter for Jetty 9.x.  You then have to provide some extra configuration in each WAR you deploy to
        Jetty.  Let's go over these steps.
    </para>
    <section id="jetty9-adapter-installation">
        <title>Adapter Installation</title>
        <para>
            Adapters are no longer included with the appliance or war distribution.Each adapter is a separate download on
            the Keycloak download site.  They are also available as a maven artifact.
        </para>
        <para>
            You must unzip the Jetty 9.x  distro into Jetty 9.x's root directory.  Including
            adapter's jars within your WEB-INF/lib directory will not work!
        </para>
    <para>
<programlisting>
$ cd $JETTY_HOME
$ unzip keycloak-saml-jetty92-adapter-dist.zip
</programlisting>
    </para>
    <para>
        Next, you will have to enable the keycloak module for your jetty.base.
    </para>
        <para>
<programlisting>
$ cd your-base
$ java -jar $JETTY_HOME/start.jar --add-to-startd=keycloak

    <section id="jetty9_per_war">
        <title>Required Per WAR Configuration</title>
        <para>
            This section describes how to secure a WAR directly by adding config and editing files within your WAR package.
        </para>
        <para>
            The first thing you must do is create a <literal>WEB-INF/jetty-web.xml</literal> file in your WAR package.  This is
            a Jetty specific config file and you must define a Keycloak specific authenticator within it.
        </para>

        <para>
            Next you must create
            a <literal>keycloak-saml.xml</literal> adapter config file within the <literal>WEB-INF</literal> directory
            of your WAR.  The format of this config file is describe in the <link linkend='adapter-config'>general adapter configuration</link>
            section.
        </para>
        <para>
            Finally you must specify both a <literal>login-config</literal> and use standard servlet security to specify
            role-base constraints on your URLs.  Here's an example:
