title: KEYCLOAK unknown authenticator error - Client Adapter installed
body: <p>I am trying to setup Keycloak with Tomcat 8.  </p>
  
  <p>I followed the instruction carefully.  I downloaded the Client Adapter for Tomcat8 and copied all the jar into $CATALINA_HOME/lib directory.  I modified my web.xml login-config to use KEYCLOAK.  Yet when I started Tomcat I kept getting Severe Error Unknown Authenticator?? </p>
  
  <p>Anywhere I googled everyone said you have to install the Client Adapter but.. in my case IT IS ALREADY THERE!!! HELP!! </p>
