I'm using Symfony 1.4 with Doctrine.

Sorry if this is a silly question but what exactly does one need to build on top of the sfDoctrineGuardPlugin to get the "remember me" functionality working?

When I login a user, the sfRemember cookie is created with the default 15-day lifetime, and the remember key is saved in the plugin's sf_guard_remember_key table.

Without any tweaks to the plugin, the sfGuardSecurityUser SignIn() method creates the cookie, but the Signout() method erases it, leaving no cookie unless you're logged in!

Signin():
sfContext::getInstance()->getResponse()->setCookie($remember_cookie, $key, time() + $expiration_age);

Signout():
sfContext::getInstance()->getResponse()->setCookie($remember_cookie, '', time() - $expiration_age);

I can see that the database table saves the cookie as a relation of sf_guard_user, but that's not much good if the cookie is gone....

I'd be grateful if someone could tell me what I'm missing here, and ideally, if I prevent the Signout() method from removing the cookie, do I need to write code to read the cookie myself or is this automated somewhere/somehow? I've got box-standard Symfony 1.4 and sfDoctrineGuardPlugin installations.

It all just seems totally wrong and the documentation on this is non-existent.

Any help would appreciated.
