Answer 1

A bit late but: I had exactly the same issue. In my case it occured because I made a mistake in the module.config.php. I placed the authentication config block inside the doctrine.driver config instead of directly inside the doctrine config.

So in my case mabe.berlin was right, the error occured because the identityClass property wasn't set.

Answer 2

From a quick view it looks like the property DoctrineModule\Options\Authentication::$identityClass is not set.

That's the reason why you get a empty class not exist error.
