authentication,login,different table name,multiple login

The Problem: Yii2 utilizes by default UserIdentity configured in config/web.php for connection, this object apply one table to authentication ('identityClass' => 'app\painel\models\User'). How to authentication from diferent tables? Solution: Create instances in web.php to uses UserIdentify. eg:
 
```php
 
  $user = \Yii::$app->user;   $school = \Yii::$app->school;   $teacher = \Yii::$app->teacher;
 
```
 
 
My config/web.php ```php
 
     'user' => [              'class'=>'yii\web\User',              'identityClass' => 'app\models\User',              'enableAutoLogin' => false,              'authTimeout' => 60*30,              'loginUrl' => ['dashboard/login'],              'identityCookie' => [                  'name' => '_panelUser',             ]
 
        ],
 
         ]
 
],
 
'school'=>[              'class'=>'yii\web\User',              'identityClass' => 'app\models\SchoolUser',              'enableAutoLogin' => false,              'authTimeout' => 60*30,              'loginUrl' => ['dashboard-school/login'],              'identityCookie' => [                  'name' => '_panelSchool',             ]
 
        ],
 
         ]
 
],
 
'teacher'=> [              'class'=>'yii\web\User',              'identityClass' => 'app\models\TeacherUser',              'enableAutoLogin' => false,              'authTimeout' => 60*30,              'loginUrl' => ['dashboard-teacher/login'],          'identityCookie' => [                  'name' => '_painelTeacher',             ]
 
         ]
 
], ``` Note that for each there is a identifyClass and one view login.
Now, we need to create the models:return '{{%user}}';
}
//// to continues.... ``` Model scholol:

```phpreturn '{{%schoolUser}}';
}
//// to continues

```return '{{%teacher}}';
}
//// to continues....

```public function behaviors()
{

 
     return [
'access' => [
'class' => AccessControl::className(),```
To use login:

 
```php //school  \Yii::$app->scholl->login($model, $this->rememberMe ? 3600*24*30 : 0);  //teacher  \Yii::$app->teacher->login($model, $this->rememberMe ? 3600*24*30 : 0);
 
```
 
 
For restrict access in views: ```php
 
<?php if (!\Yii::$app->scholl->isGuest):?> <h1>My scholol Name: <?=\Yii::$app->scholl->identity->name?>
<?php endif;?><h1>Teacher Name: <?=\Yii::$app->teacher->identity->name?>
<?php endif;?>

 
``` Always use the specific instance of the user you want to work with.
