MySQL Question

Symfony2 - Access is denied (user is not fully authenticated)

I'm developing a website using Symfony2, and until today - had no problem logging in. But now when logging in I'm not correctly authenticated - Symfony profiler lists me as

logged in as: anon
instead of the user I logged in as. I'm also redirected back to the login page instead of the target path.

The login process consists of a traditional login form (i.e. username + password) with a submit button. All user credentials are stored in MySQL and I've setup a User entity as a provider.

There are no errors in my php errors log, or listed in the Symfony profiler under Exception or Logs.

One observation I've made is nothing is listed under the Session Attributes heading (within Symfony profiler > Request) - normally there would be some security context information listed after successfully logging in, but now it's always empty. I tried setting a basic session variable on the homepage which was partially successful as it gets set and is shown under Session Attributes, but get's cleared whenever attempting to login!

This is my security.yml file:

# app/config/security.yml

Woodcut\UserBundle\Entity\User: sha512


entity: { class: Woodcut\UserBundle\Entity\User, property: username }

pattern: ^/
anonymous: ~
login_path: login
check_path: login_check
username_parameter: _username
success_handler: custom_authentication_handler
failure_handler: custom_authentication_handler
#always_use_default_target_path: true
#default_target_path: /login_router
path: /logout
target: /
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false

- { path: ^/admin, roles: ROLE_ADMIN }
- { path: ^/ratings/update, roles: ROLE_USER }
- { path: ^/ratings/new, roles: ROLE_USER }
- { path: ^/favourite, roles: ROLE_USER }

I'm using a typical LAMP stack to run my site with Symfony 2.3.13 and PHP 5.4.28 on a Ubuntu 12.04 Virtual machine. PHP is running as mod_php.

Output from Symfony Profiler > Debug:

INFO - Populated SecurityContext with an anonymous Token
DEBUG - Notified event "kernel.exception" to listener "Symfony\Component\Security\Http\Firewall \ExceptionListener::onKernelException".
DEBUG - Access is denied (user is not fully authenticated) by "/vagrant_www/vprojects/woodcut/vendor/symfony/symfony/src/Symfony/Component/Security/Http/Firewall/AccessListener.php" at line 70; redirecting to authentication entry point
DEBUG - Calling Authentication entry point

If someone can please help me determine why users are authenticated as anonymous instead of as themselves that would be great. Been pulling my hear out the last two days trying to find the cause.

Thanks in advance for any help provided!

Additional info: I have a VPS running a copy of the site (for client previewing). I dev on my local VM and
git push
my changes, I then SSH into my VPS and do a
git pull
to keep my two version in sync.

What's strange is the VPS version does not exhibit this issue (i.e. login works fine) yet both versions use an identical codebase except for some minor differences in their respective parameters.yml and parameters_dev.yml files.

Update: Problem started happening after making a large number of edits to the code base and performing a
apt-get update
apt-get upgrade
on my VM. So in an effort to isolate the possible cause I rolled back to an earlier commit - to see if the problem was code related. But despite rolling back to before my major coding changes, the problem is still there.

This has me thinking the cause may not be code related and instead could be server related, something in the new version of PHP (5.4.28) that was installed via
apt-get upgrade
perhaps OR a new php.ini directive maybe?

I've run the Symfony configuration checker tool and everything seems fine!

I was struggling with the same problem. I checked almost everything and after that suspecion fell on session handler...

I have

session: ~

changed to:

    handler_id:  ~
