Hi,

I am evaluating keycloak and running into this issue when deploying a web application secured using keycloak:

14:12:59,436 INFO  [org.jboss.web] (ServerService Thread Pool -- 80) JBAS018210: Register web context: /customer-portal

14:12:59,445 ERROR [org.apache.catalina.startup] (ServerService Thread Pool -- 80) JBWEB001034: Cannot configure an authenticator for method KEYCLOAK

14:12:59,446 ERROR [org.jboss.web] (ServerService Thread Pool -- 80) JBAS018206: Webapp [/customer-portal] is unavailable due to startup errors

I have updated the customer-app/src/main/webapp/WEB-INF/web.xml app with following login-config parameter

    <login-config>

        <auth-method>KEYCLOAK</auth-method>

        <realm-name>demo</realm-name>

    </login-config>

I have followed the instructions @ http://docs.jboss.org/keycloak/docs/1.0-beta-3/userguide/html_single/#WAR_distribution_installation and using the following versions of the software:

jboss-eap-6.2

keycloak-war-dist-all-1.0-beta-3

I have in addition to the instructions above, 

cd $JBOSS_HOME

unzip ~/opt/keycloak/keycloak-war-dist-all-1.0-beta-3/adapters/keycloak-eap6-adapter-dist-1.0-beta-3.zip
