$authService->setAdapter($authAdapter);
$authService->setStorage($sm->get('Application\Model\SoapAuthenticationStorage'));
return $authService;
}
)
);
}
Any help to solve this

Answer 1

Each of the set methods in your adapter need to return $this in order to allow you to chain method calls together (this is called a 'fluent interface'). E.g.:
public function setIdentity($username)
{
$this->username = $username;
return $this;
}
That should fix the error you're getting.
