I've pinpointed the cause of my problem and have been able to fix (or at least work around it).

After receiving a signout request my server sends back HTML with a reference to a CSS stylesheet. (In my case the reference is to an IE specific CSS file, and the reference was bad so it wasn't being cached by the client). The request for the CSS file from the clien apparently contained the rememberMe cookie, so the value of the cookie was again associated with the client.

I don't know enough details about the HTTP specification to know if this means there is a bug with IE, JSecurity, or whether my case was so unusual that it just isn't worth worrying about.

Thanks,

Brad

I'm still blocked by this issue and would appreciate any suggestions. The problem is that SpringJSecurityFilter is being executed a second time during my signOut request. I have no idea why this is happening. (The parent class OncePerRequestFilter cannot really fulfill the mission that its name implies. The request.setAttribute() value that is set during the first execution is not present during the second execution.) response.isCommitted() is also false during the second execution so the strategy from JSEC-58 is of no use in this case.

I don't understand enough about the servlet filter mechanism to understand why the filter is being executed twice, or how to stop it. I'm also not clear if this is a Grails related problem or not.

I have determined that my problem only occurs with IE -- it does not happen with other browsers such as Firefox.

Thanks,

I got some help from the Grails list that enabled me to set the init-param on DispatcherServlet. (Actually, it's a subclass in Grails called GrailsDispatcherServlet). Unfortunately neither this change nor my patch has solved my problem.

I've been looking at my logs and it seems that at the very end of request processing (i.e. after a Grails filter 'afterView' method has fired) that Grails is unbinding the request from a thread, and then binding the request to a new thread. Something is then calling JSecurity code (including WebRememberMeManager). At this point the "logged out" flag is no longer associated with the request, and the cookie is read again.

Here's some relevant log output:

Oops - you might have missed Jeremy's response:

"In my case, Spring was calling request.getUserName(), which under the hood called JSecurity's getSubject(). To stop this from happening I had to set the publishEvents init-param to false on my Spring DispatcherServlet, which

Try that.  We'll get on the issue and fix it.

Thanks,

Thanks for the response. This is a blocker for me. I disabled all of my explicit getSubject() calls but perhaps something else is still making the invocation. Would any Spring application be making this call? (In other
words, would any Grails app being making the same call that you saw?)

Thanks,

Brad

I just ran into this same problem. I think it is a JSecurity bug. The problem is that if any methods invoke getSubject() after logout() is called, but during the same request, a new subject will be created. But since the remember me cookie is still present, the subject gets created in the new
Session with the remembered principals.

The problem doesn't occur if getSubject() isn't called after logout(). In my case, Spring was calling request.getUserName(), which under the hood called JSecurity's getSubject(). To stop this from happening I had to set the publishEvents init-param to false on my Spring DispatcherServlet, which
stopped Spring from calling the getUserName() function.

Still - this shouldn't be necessary and I think the onus is on JSecurity to figure out how to make this not happen. Perhaps we can set a request attribute that causes the remember me cookie to not be honored for the remainder of that request. Any other ideas for how to work around this
problem?

I filed a bug report here: https://issues.apache.org/jira/browse/JSEC-57

 I'm having a problem that I don't fully understand. After I invoke
logout() the subject.principal becomes null as expected, but upon redirect the subject.principal is no longer null -- the user is remembered again. The log messages from JSecurity indicate a rememberMe cookie has been found when
I think it probably shouldn't be found.

The issue does not occur in my devel environment (Grails, HSQLDB) but only in production (Tomcat, MySql, war deployed as ROOT). My signout code
does this:

         log.info "signout: enter:
 getPrincipal=${SecurityUtils?.getSubject()?.getPrincipal()}"
         SecurityUtils.subject?.logout()
         log.info "signout: after logout:
 getPrincipal=${SecurityUtils?.getSubject()?.getPrincipal()}"
         redirect(controller: 'home')

My log shows this. (You'll notice that I have several 'before' and
'after' filters)

Is this a bug in JSecurity or am I doing something wrong? Is there a work
around for this?
