Laravel Shibboleth Service Provider

This package provides Shibboleth authentication for Laravel.

For development, it can emulate an IdP (via mrclay/shibalike).

Pre-Requisites

In order to use this plugin, we assume you already have a pre-existing Shibboleth SP and Shibboleth IdP configured. This does not (and will not) go into explaining how to set that up.

However, this might be helpful: https://github.com/razorbacks/ubuntu-authentication/tree/master/shibboleth

Installation

Use composer to require the latest release into your project:

composer require razorbacks/laravel-shibboleth

If you're running Laravel >= 5.5, then you can skip this step, otherwise you will need to manually register the service provider in your config/app.php file within the Providers array.

StudentAffairsUwm\Shibboleth\ShibbolethServiceProvider::class,

If you you would like to use the emulated IdP via shibalike, then you will need to manually register it on any version - this is not automatically loaded even in Laravel 5.5.

StudentAffairsUwm\Shibboleth\ShibalikeServiceProvider::class,

Note that the password is the same as the username for shibalike.

Publish the default configuration file:

php artisan vendor:publish --provider="StudentAffairsUwm\Shibboleth\ShibbolethServiceProvider"

Optionally, you can also publish the views for the shibalike emulated IdP login:

php artisan vendor:publish --provider="StudentAffairsUwm\Shibboleth\ShibalikeServiceProvider"

University of Arkansas Users:

To also logout with the IdP, set the the following in config/shibboleth.php

'idp_logout' => '/Shibboleth.sso/Logout?return=https%3A%2F%2Fidp.uark.edu%2Fidp%2Fexit.jsp',

Change the driver to shibboleth in your config/auth.php file.

'providers' => [
    'users' => [
        'driver' => 'shibboleth',
        'model'  => App\User::class,
    ],
],

Now users may login via Shibboleth by going to https://example.com/shibboleth-login and logout using https://example.com/shibboleth-logout so you can provide a custom link or redirect based on email address in the login form.

@if (Auth::guest())
    <a href="/shibboleth-login">Login</a>
@else
    <a href="/shibboleth-logout">
        Logout {{ Auth::user()->name }}
    </a>
@endif

You may configure server variable mappings in config/shibboleth.php such as the user's first name, last name, entitlements, etc. You can take a look at them by reading what's been populated into the $_SERVER variable after authentication.

<?php print_r($_SERVER);

Mapped values will be synced to the user table upon successful authentication.

Declare Login Route

By convention, laravel assumes a route named login exists to redirect unauthenticated requests.

This package names its route shibboleth-login because it's designed to work alongside other authentication providers, such as the default scaffolding provided by artisan. But if this is the only authentication provider, then that name will need to be manually declared. e.g.

Route::name('login')->get('/login', '\\'.Route::getRoutes()->getByName('shibboleth-login')->getActionName());

or more readable, but with a redirect:

Route::redirect('/login', '/shibboleth-login')->name('login');

Authorization

You can check for an entitlement string of the current user statically:

$entitlement = 'urn:mace:uark.edu:ADGroups:Computing Services:Something';

if (Entitlement::has($entitlement)) {
    // authorize something
}

Now you can draft policies and gates around these entitlements.

Local Users

This was designed to work side-by-side with the native authentication system for projects where you want to have both Shibboleth and local users. If you would like to allow local registration as well as authenticate Shibboleth users, then use laravel's built-in auth system.

php artisan make:auth

JWTAuth Tokens

If you're taking advantage of token authentication with tymon/jwt-auth then set this variable in your .env

JWTAUTH=true
