Laravel SAML Single Sign-On (SSO) plugin gives the ability to enable SAML Single Sign-On for your laravel applications. Using Single Sign-On you can use only one password to access your laravel application and services. Our plugin is compatible with all the SAML compliant Identity providers. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between Laravel and Okta considering Okta as IdP.

Pre-requisites : Download And Installation

• Open a Command Prompt window and change the working directory to your Laravel app's main directory.
• Enter the below command.

  composer require miniorange/saml-laravel-free



• Note: If you are using Laravel 5.4 or below, you will need to add the following value to the 'providers' array in your app.php file which can be found in the project\config folder :provider\ssoServiceProvider::class (You can check your current Laravel version by using the command php artisan --version.)


• After successful installation of package, go to your Laravel app in the browser and enter https://<your-host>/mo_admin in the address bar.
• The package will start setting up your database for you and then redirect you to the admin registration page.
• Register or log in with your account by clicking the Register button to configure the plugin.

• After login, you will see the Service Provider Settings option, where you will get the service provider metadata. Keep the metadata handy as it will be required later to configure step 1.
