Does you device have double authentication. i.e. Once you've logged in via SSH you are then asked for login/password again? If so have you set these values in the appropriate field for CatTools? From the debug it looks like when the Password: prompt appears nothing is sent, which suggests maybe the VTY password prompt is empty.
no the alliedware plus does not have an extra login for e enable.
just the initial login and password gives an prompt
enable does not require extra credentials
