No auth working at android and ios clients

Hello,
I can't authenticate the User if the Client is an Apple device (Built in Client) or an android device (DAVx App). At the Service file inside the LaravelSabre::auth function is always the error auth()->user() is null.

Where can i add the function to authorize Android and iOS Clients too. At the web frontend always Works good with the authorization.

Sorry for my Bad englisch.
