[keycloak-user] MongoDB and removing datasource KeycloakDS

Hi everybody, I'm tryng to use keycloak withh mongo. I followed the documantation: http://docs.jboss.org/keycloak/docs/1.0-alpha-3/userguide/html/server-ins... But removing datasource KeycloakDS from standalone/configuration/standalone.xml causes an error message: 13:10:56,838 INFO [org.jboss.as.jpa] (MSC service thread 1-1) JBAS011401: Read persistence.xml for jpa-keycloak-identity-store 13:10:57,321 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014613: Operation ("deploy") failed - address: ([("deployment" => "auth-server.war")]) - failure description: {"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.persistenceunit.\"auth-server.war#jpa-keycloak-identity-store\".__FIRST_PHASE__ is missing [jboss.naming.context.java.jboss.datasources.KeycloakDS]"]} Suggestions?
