I'm trying to follow the 'Getting Started' procedure of the latest (15.0.2) Keycloak.

Using the WildFly 25.0.0.Final, updated with keycloak-oidc-wildfly-adapter-15.0.2

The WildFly error happens when installing the app-profile-jee-vanilla quickstart sample, while running the command 'mvn clean wildfly:deploy':

19:58:05,514 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 80) MSC000001: Failed to start service jboss.deployment.unit."vanilla.war".undertow-deployment: org.jboss.msc.service.StartException in service jboss.deployment.unit."vanilla.war".undertow-deployment: java.lang.RuntimeException: java.lang.IllegalStateException: The required mechanism 'KEYCLOAK' is not available in mechanisms [BASIC, CLIENT_CERT, DIGEST, FORM] from the HttpAuthenticationFactory.
at org.wildfly.extension.undertow@25.0.0.Final//org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:90)

As far as I see the KEYCLOAK mechanism is present in the http-authentication-factory section of standalone.xml config file. Any idea, why it's not available ?

According with this article, to Wildfly 25 it not necessary install any adapder, but the in web.xml the name must be OIDC instead KEYCLOAK.

   <auth-method>OIDC</auth-method>
