[jboss-jira] [JBoss JIRA] (WFLY-5484) Calling HttpServletRequest.logout() with single sign-on enabled only works every second time

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13145989#comment-13145989 ] 

Paul Ferraro commented on WFLY-5484:
------------------------------------

This issue seems to be due to a conflict between Undertow's CachedAuthenticatedSessionMechanism and SingleSignOnMechanism.  If the CachedAuthenticatedSessionMechanism detects an AuthenticatedSession in the HttpSession, the SingleSignOnMechanism never has the chance to register a security notification listener, thus the SSO is not invalidated on logout.  Reassigning this to [~swd847] as this is clearly an issue with Undertow security, not with clustering SSO management.

> See "Steps to Reproduce". Logging out from an application only works every second time, e.g. HttpRequestServlet.logout() has to be called twice in order to have any effect
> This doesn't occur without <single-sign-on/> enabled - logout() has the expected effect. The issue is security related, thus I'm adding our security team members as watchers.
