Hello Sebastien,


You saved my life!!!


I manually modified the keycloak-tomcat8-adapter-2.3.0.Final file and it worked perfectly.


public class KeycloakAuthenticatorValve

  extends AbstractKeycloakAuthenticatorValve


  public boolean authenticate(Request request, HttpServletResponse response)

    throws IOException


    return authenticateInternal(request, response, request.getContext().getLoginConfig());



  protected boolean doAuthenticate(Request request, HttpServletResponse response)

    throws IOException


    return authenticate(request, response);



  protected boolean forwardToErrorPageInternal(Request request, HttpServletResponse response, Object loginConfig)

    throws IOException




This will fix the problem while the new version arrives.


Server: Apache Tomcat (TomEE)/8.5.6 (7.0.2)


Thank you very much.

Is your TomEE version using Tomcat 8.5.5 ? Because it looks like a really similar issue https://issues.jboss.org/browse/KEYCLOAK-3669?filter=-2 and this is fixed andshould be available in the next release

Hello community:

I have secured my application on an Apache 8 server, following the steps,
but when accessing a protected resource I hope to be redirected to Keycloak
but nothing happens.

I'm getting this error (HTTP CODE 500)

Nov 18, 2016 1:02:19 AM org.apache.catalina.authenticator.FormAuthenticator
WARNING: No login page was defined for FORM authentication in context [/

I added the keycloak.json file in the WEB-INF and the context.xml file in
the META-INF. I have also done my security settings on the web.xml.



  "realm": "expocafe",

  "auth-server-url": "http://localhost:8080/auth",

  "ssl-required": "external",

  "resource": "sis",

  "credentials": {

    "secret": "8ccc6994-2e05-48d3-9aea-f6f31beb2819"




<?xml version='1.0' encoding='utf-8'?>

<Context path="/sis">

className="org.keycloak.adapters.tomcat.KeycloakAuthenticatorValve" />





                    <web-resource-name>Secured pages</web-resource-name>











       <!-- Rol definido en Keycloak para permitir el acceso basico a la
aplicacion -->




What could I check?

Keycloak v2.3.0.Final

Apache Tomcat 8.5
