CAS

CAS server SSO authentication in Laravel 4.x & 5.x

Installation

Require this package in your composer.json and run composer update.

For Laravel 4 use v1.1.* :

"xavrsl/cas": "1.1.*"

For Laravel 5 use v1.2.* :

"xavrsl/cas": "1.2.*"

After updating composer, add the ServiceProvider to the providers array:

For Laravel 4:

app/config/app.php

    'Xavrsl\Cas\CasServiceProvider',

As well as the Facade :

	'Cas' => 'Xavrsl\Cas\Facades\Cas',

For Laravel 5:

config/app.php

    Xavrsl\Cas\CasServiceProvider::class,

As well as the Facade :

	'Cas'       => Xavrsl\Cas\Facades\Cas::class,

Then publish the package's config using one of those methods :

For Laravel 4 :

    $ php artisan config:publish xavrsl/cas

For Laravel 5 :

    $ php artisan vendor:publish

Configuration

Configuration should be pretty straightforward for anyone who's ever used the phpCAS client. Using the .env file will allow you to have different environments without even touching the cas.php config file. I've added the possibility to easily turn your application into a CAS Proxy, a CAS Service or both. You only need to set the cas_proxy setting to true (if you need to proxy services) and set the cas_service to whatever proxy you want to allow (this is all explained in the config file).

A new config variable (cas_pretend_user) available in the 1.2 release allows you to pretend to be a selected CAS user. The idea came with the usage of laravel homestead. My application was running on a private network, on a fake domain. The CAS server was not able to redirect to that application. So activating the CAS plugin on that application was not possible, but I needed a user id to query my LDAP and allow/disallow the user in my application. You only need to give it a user id and the application will act just as if you ware logged in with that CAS user.

Usage

Authenticate against the CAS server. This should be called before trying to retrieve the CAS user id.

	Cas::authenticate();

Then get the current user id this way :

	Cas::getCurrentUser();

OR

  Cas::user();
