So I'm attempting to authenticate my user's using Laravel's custom filters. I have my LDAP PHP script working and I have essentially plugged it in to my custom filter. However, I need to pass this script the username and password that the user enters on the log in screen; in other words, I need to pass my custom filter this username and password from the log in form.

Here is my code to help explain my problem:

routes.php

Route::group(array('before' => 'ldapTest'), function() {
    Route::controller('apps', 'AppController', array(
        //named routes here
    ));
});

filters.php

Route::filter('ldapTest', function()
{
    $username = //how do I get this?
    $password = //how do I get this?

    //LDAP logic goes here; assume $ldapConn and $userDN are properly initialized
    $userBind = @ldap_bind($ldapConn, $userDN, $password);
        
    if($userBind)
    {
        Auth::login(//What goes here? I want to access $username later on in applications);
        return Redirect::to('apps/home');
    }
    else
    {
        echo 'Incorrect password';
    }
});

From reading the documentation I understand you can pass parameters as strings to filters like so: Route::filter('ldapTest:400', function(), but I don't understand how I could use this to pass my username and password using what I assume would be Input::get().

How can I do this?
