How to log users off automatically after a period of inactivity?

Question

After a lot of search in the web and find nothing, I wonder if there is an easy way to automatic logout the user logged through the Symfony Security after an inactive period

Answer 1

Works perfect with FOSUserbundle, thank you.

I added this to the inner condition to prevent the anonymous user to get logged out.

...

$isFullyAuthenticated = $this->securityContext->isGranted('IS_AUTHENTICATED_FULLY');

if ($lapse > $this->maxIdleTime && $isFullyAuthenticated == true) {

 ... do logout / redirect etc.

}
