Because I am working with legacy tables, I wrote my own Auth_Adapter, named User_Auth_Adapter_DbTable. I have a module user and I want to have this class there.
However, I have no idea where to actually put the file and how to name it so the Zend autoloader can find it. I have googled for more than an hour and did not find a hint, so I put it under /application/modules/user/controller/Auth/Adapter/DbTable.php, because it is used by the controller there. But it is not found.
Can you share some code from adapter? I think logically it must be in models folder. And the name of this class should follow Zend Framework naming conventions. So if you will put it to models/user/auth/adapter/DbTable.php class should be named as Model_User_Auth_Adapter_DbTable
