Deploy the attached war, or build from https://github.com/stianst/jboss-as-quickstart/tree/clustered_sso_test/servlet-security Open http://localhost:8080/jboss-as-servlet-security/SecuredServlet and login (username is first box, password second) Now press "logout" (this calls Request.logout). You will now see "Logged out". Refresh the page and observer that the user has been reauthenticated from ssoId in the SSO cluster. The workaround has been added to this example as well, press "invalidate" instead of "logout" (this calls Session.invalidate before calling Request.logout).
