`<?php error_reporting(E_ALL); ini_set('display_errors', 1); error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE); require_once DIR . '/vendor/autoload.php';

session_start();

$config = [ 'authentication' => [ 'ad' => [ 'client_id' => '----------------', 'client_secret' => '2F3-----------------', 'redirect_url' => 'https://----------------.azurewebsites.net/login/', 'enabled' => '1', 'directory' => '----------------d0e5' ] ] ];

$request = new \Zend\Http\PhpEnvironment\Request();

$ad = new \Magium\ActiveDirectory\ActiveDirectory( new \Magium\Configuration\Config\Repository\ArrayConfigurationRepository($config), Zend\Psr7Bridge\Psr7ServerRequest::fromZend(new \Zend\Http\PhpEnvironment\Request()) );

$entity = $ad->authenticate(); echo $entity->getName() . '<Br />'; //echo $entity->getOid() . '<Br />'; echo $entity->getPreferredUsername() . '<Br />'; ?>`

Despite having defined redirect_url is am still getting the below error;

Fatal error: Uncaught League\OAuth2\Client\Provider\Exception\IdentityProviderException: invalid_client in D:\home\site\wwwroot\login\vendor\league\oauth2-client\src\Provider\GenericProvider.php:216 Stack trace: #0 D:\home\site\wwwroot\login\vendor\league\oauth2-client\src\Provider\AbstractProvider.php(644): League\OAuth2\Client\Provider\GenericProvider->checkResponse(Object(GuzzleHttp\Psr7\Response), Array) #1 D:\home\site\wwwroot\login\vendor\league\oauth2-client\src\Provider\AbstractProvider.php(560): League\OAuth2\Client\Provider\AbstractProvider->getResponse(Object(GuzzleHttp\Psr7\Request)) #2 D:\home\site\wwwroot\login\src\Delegates\Receive.php(81): League\OAuth2\Client\Provider\AbstractProvider->getAccessToken(Object(League\OAuth2\Client\Grant\AuthorizationCode), Array) #3 D:\home\site\wwwroot\login\src\ActiveDirectory.php(179): Magium\ActiveDirectory\Delegates\Receive->execute() #4 D:\home\site\wwwroot\login\index.php(28): Magium\ActiveDirectory\ActiveDirectory->authenticate() #5 {main} thrown in D:\home\site\wwwroot\login\vendor\league\oauth2-client\src\Provider\GenericProvider.php on line 216
