+## [Laravel 5.2++] Oracle User Provider
+When using oracle, we may encounter a problem on authentication because oracle queries are case sensitive by default. 
+By using this oracle user provider, we will now be able to avoid user issues when logging in and doing a forgot password failure because of case sensitive search.
+
+To use, just update `auth.php` config and set the driver to `oracle`
+```php
+'providers' => [
+	'users' => [
+		'driver' => 'oracle',
+		'model' => App\User::class,
+	],
+]
+```
