Shibboleth-Laravel authentication bridge

Shibboleth authentication typically results in the identity provider setting a bunch of server variables after successful authentication. This is a Laravel 5.0+/PHP 5.4+ package helps with converting those server tokens into Laravel User Table fields so that regular Laravel semantics of authentication can be followed.

Note that shib auth must already have occured - usually using directives in the .htaccess file.

The included middleware checks the user table and

If a matching user is NOT found, it creates a new user row
If a user is found in the users table, the corresponding user record is retrieved
The user is then logged in to the application using Auth::login($user)

Installation

require the package via composer

$ composer require mnshankar/laravel-shib-auth

Next, setup the service provider. This allows you to modify the config file (the default tokens are specific to UF implementation of Shibboleth)

In your config/app providers array, add:

'mnshankar\Shib\ShibAuthServiceProvider',

You must insure that

The mapped fields exist in your users table.
Shibboleth sets valid values for all tokens specified (else exception is thrown)
"password" field in the users table must be nullable as we will not be using it.

Usage

Edit your http kernel.php file to include the shib middleware from the package like so:

'shib'=>'mnshankar\Shib\Middleware\ShibAuth',

Now, you can use the middleware either from the controller or from your route.

In your controller:

function __construct()
{
    $this->middleware('shib');
}

In your route:

Using Laravel 5.0
```
Route::get('my/page', ['middleware' => 'shib', function()
{
    //
}]);
```
Using Laravel 5.1+

You can continue using Laravel 5.0 style.. or use chaining:
```
Route::get('/', function () {
    //
})->middleware(['shib']);
```
You may also use route groups. Please look up Laravel documentation on Middleware to learn more https://laravel.com/docs/5.2/middleware

Configuration Options

You can customize the configuration options by publishing them

php artisan vendor:publish --provider="mnshankar\Shib\ShibAuthServiceProvider"
