Having trouble with custom login flow in Symfony 2

Question

First I'll explain what I'm trying to accomplish:

• users navigate to "/login" in my application
• a nonce is generated, and used to created a URL to redirect users to an external service
• users authenticate with the external service, and are redirected back to my application with a GET parameter
• the GET parameter is validated using the nonce , and user info is retrieved from the external service
• the user is loaded from my application's database (or created if they don't exist) and logged in
• after logging in, user roles dictate what this user has access to

I had originally implemented this via controller actions where a loginAction does the redirecting to the external service, and the external service redirects back to an authAction. In the authAction, the user is loaded (or created) and programatically logged in.

I thought the previous approach might be hack-ish, and attempted to try the SimplePreAuth tutorial , but I'm having no luck.

What would be my best approach?
