[Login] Why it's necessary to have a phpsessid to login? #3703

joanteixi opened this Issue Mar 27, 2012 · 13 comments

We're in a scenario where there is a login form created by Sencha, that sends username and password directly to login_check. We created an own Listener to bypass the csrf protection. The first time you do login, the AbstractAuthenticationListener throws an exception:

            if (!$request->hasPreviousSession()) {
                throw new SessionUnavailableException('Your session has timed-out, or you have disabled cookies.');

Wich will be the best approach to resolve this?

So far, we had to make it as a workaround...


nice. I didn't know that was possible create a session like you do in the listener. Thks, i will try.

gillest commented Apr 20, 2012

Well, to tell you the truth, I would fully prefer an answer/solution from @schmittjoh cause it remains an horrible hacky solution...


oh... maybe... but my solution was worst... belive me... (something like redirect to an empty action... glups...)

By the way, seeing the message "Your session has timed-out, or you have disabled cookies.", I made a use case trying to make raise a time-out on the server side: the message is not displayed which is bad.
If this is not a security check, this seems to be even more useless...
We wait a bit more cause I do not want to make a PR without any answer from @schmittjoh .

@schmittjoh Would you please give us an answer?

Dattaya commented May 25, 2012

I'd like to hear schmittjoh's answer too.

Any progress on this issue? It causes problems if we want to use a caching system (i.e when the session auto_start is off).


+1 me interesting too
@gillest solution working fine, just don't forget to clear cache for production environment

@schmittjoh I would really appreciate your opinion on this issue.

Sessions are now auto-started and people are even more likely not to have a previous session when they submit their login form.

I can not understand why this check is here: you have to submit the form to trigger the listener so I think it is useless.

The question is: can this check be removed, if not why is it useful here (and should we move it somewhere else) ?

Thanks for your help.

@vicb I think it can be safely removed from the AbstractAuthenticationListener. The next method called in the sequence is the abstract attemptAuthentication() method. Listeners that inherit from the class can check for a previous session in there and throw the appropriate exception if needed. In core the UsernamePasswordFormAuthenticationListener would only have to check for that if a csrf provider is injected.

It would be a BC break though for people implementing their own listeners that do depend on a previous session being active.

If you want to go through with it I'd be happy to send a PR.

@schmittjoh Am I seeing this correctly?

[2.2] [Security] Add an option to disable the hasPreviousSession() check in AbstractAuthenticationListener

Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: [![Build Status](](
Fixes the following tickets: #3703
Todo: Add this option to the symfony doc security configuration reference
License of the code: MIT
Documentation PR: N/A

As stated in #3703, all authentication listeners that inherit from AbstractAuthenticationListener, only work when a previous session has been created.
This PR allows to change the default behavior in the security.yml file.


            pattern:    ^/demo/secured/
                check_path: /demo/secured/login_check
                login_path: /demo/secured/login
                require_previous_session: false # The default value is true
                path:   /demo/secured/logout
                target: /demo/
            #anonymous: ~
            #    realm: "Secured Demo Area"
