in StackOverflow already googled and found nothing that could help me.

always got the error: AclNode :: node () – Could not find Aro node Identified by “Array ([Aro0.model] => User [Aro0.foreign_key] =>)”

believe that somehow the ForeignKey of groups is not being set … but I can not find where to set it.

Answer

Do you have group_id(of course with username and password) column in your array, that is used to login ? I mean this line

$this->Auth->login($this->request->data))

$this->request->data should contain array like

array('username' => 'my_username', 'password' => 'password', 'group_id' => '1')
