title: What is the listener called after login ?
body: <p>I need to find a user in a webservice, so I need to modify the default Symfony Security  Listener.
  I am using FOSUserBundle in my project.</p>
  
  <p>I have found the Listener LastLoginListener that's fine I will need to modify this one too but first I need to find the code who is looking for the user login, password ect ... </p>
  
  <p>I need to do something like this :
  Do a request at a webservice : If User is found there, I update my own User with new informations and I login this User.</p>
  
  <p>Have any idea what I need to modify ? </p>
  
  <p>Sorry for my bad english, not my native language.</p>
