When you have a Vue.js powered app authentication using traditional logon pages isn’t going to work. This is because primarily the apps interaction with the server is using Ajax calls with axios. So now we need to use JSON Web Tokens (JWT) to handle the authentication and store a client side session authentication token.

This article is very useful for this: https://codeburst.io/api-authentication-in-laravel-vue-spa-using-jwt-auth-d8251b3632e0

It didn’t cover all of the aspects in my case as I’m using Laravel 5.5. So some of the changes I needed to make were in regard to that.

In particular I had to switch to using the development branch of the jwt-auth project as linked in the article taking you here: https://github.com/tymondesigns/jwt-auth/issues/1298

In the header of the AuthController needed to include:

use Auth;
use App\User;
use JWTAuth;

I then had to amend the User model to include the trait JWTSubject

use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements JWTSubject

and add to it the two functions/methods as detailed here http://jwt-auth.readthedocs.io/en/docs/quick-start/#update-your-user-model

     * Get the identifier that will be stored in the subject claim of the JWT.
     * @return mixed
    public function getJWTIdentifier()
        return $this->getKey();

     * Return a key value array, containing any custom claims to be added to the JWT.
     * @return array
    public function getJWTCustomClaims()
        return [];

Now all I have to do is figure out how to authenticate by user name not email address. Then switch from the database authentication to LDAP.
