Your auth component configuration is incorrect. You are missing the appropriate userModel option, which defines the name of the model to use
And the fields configuration doesn't work the way your are using it, the keys must be named username and password, and the value can then contain the actual column name, however since your columns are obviously using the default names, there's no need to use this option at all.
$this->Auth->authenticate = array(
'Form' => array (
'scope' => array('ChatUser.is_active' => 1),
'userModel' => 'ChatUser'
)
);
Also the session key will always be Auth.User unless you are explicitly changing it via AuthComponent::$sessionKey:
$this->Auth->sessionKey = 'Auth.ChatUser';
However, you are better of using the auth component to access the user data anyways:
// Use anywhere
AuthComponent::user('id')
// From inside a controller
$this->Auth->user('id');
