In the above we assume that our ids are like `customer-23` or `supplier-34`. When we need to get identity instance we split the id by `-` and getting both type and integer id for the model corresponding to that type.

Having identity we can tell Yii to use it via `confing/main.php`:

```php
[...]
{
if ($this->_user === false) {
$this->_user = Identity::findIdentityByEmailByUsername($this->username);
}

return $this->_user;
}
}
