Got most of the errors fixed can't get my head around this...

ErrorException in CustomUserProvider.php line 24:
Argument 1 passed to App\Auth\CustomUserProvider::__construct() must be an instance of App\Auth\Webservice\AuthCheckApi, instance of App\User given, called in /Applications/MAMP/htdocs/forms/app/Providers/CustomAuthProvider.php on line 18 and defined

Part of CustomUserProvider.php

<?php namespace App\Auth;

use Illuminate\Contracts\Auth\User as UserContract;
use Illuminate\Contracts\Auth\UserProvider as UserProviderInterface;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Auth\GenericUser;

class CustomUserProvider implements UserProviderInterface {
	/**
  * External webservice for authentication
  */
  private $webservice;
   /**
  * The user object.
  */
  private $user;

    /**
  * Constructor

  */
  public function __construct(\App\Auth\Webservice\AuthCheckApi $webservice)
  {
      $this->webservice = $webservice;
      $this->user = null;
  }

AuthCheckApi is part of this Api file....

<?php

namespace App\Auth\Webservice;

require_once('nusoap/nusoap.php');

class LimoApiBase{

    protected $_apiKey = "*********************";
    protected $_apiId = "***********************";

    protected $_wsdl = null;

    public function __construct(){
        //$this->_apiKey = $apiKey;
        $this->_client = new \nusoap_client($this->_wsdl, true);
    }

    public function getClient(){
        return $this->_client;
    }
