[keycloak-user] UT010039: Unknown authentication mechanism KEYCLOAK

Hi all I am getting the below message with KeyCloak 1.5.0/WF9.0.1 overlay installation. My configuration file looks exactly the same as the stock one, e.g: <extensions> ... <extension module="org.keycloak.keycloak-server-subsystem"/> ... </extensions> ... <profile> ... <subsystem xmlns="urn:jboss:domain:keycloak-server:1.1"> <web-context>auth</web-context> </subsystem> </profile> The module jars are properly put in the WF folders My web.xml also seems right too: ========================================= <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!-- Default page to serve --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- This error page rule responds with the GWT Host page for pushstate Errai Navigation URLs --> <error-page> <error-code>404</error-code> <location>/</location> </error-page> <!-- Erray Keycloak security --> <filter> <filter-name>ErraiLoginRedirectFilter</filter-name> <init-param> <param-name>redirectLocation</param-name> <param-value>/index_draft.jsp</param-value> </init-param> </filter> <!-- JAX-RS configuration--> <servlet-mapping> <servlet-name>javax.ws.rs.core.Application</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> <filter-mapping> <filter-name>ErraiUserCookieFilter</filter-name> <url-pattern>/index_draft.jsp</url-pattern> </filter-mapping> <filter-mapping> <filter-name>ErraiLoginRedirectFilter</filter-name> <url-pattern>/app-login</url-pattern> </filter-mapping> <security-constraint> <web-resource-collection> <web-resource-name>Login</web-resource-name> <url-pattern>/app-login</url-pattern> </web-resource-collection> <auth-constraint> <role-name>*</role-name> </auth-constraint> </security-constraint> <login-config> <auth-method>KEYCLOAK</auth-method> <realm-name>whatever</realm-name> </login-config> <security-role> <role-name>user</role-name> </security-role> <security-role> <role-name>admin</role-name> </security-role> </web-app> I can access the KC admin console and configure realms/users/roles no problem in the WF 9.0.1 server.* I am out of ideas of what could be causing it. Any hints?
