CakePHP Authentication Plugin Identity Associations - authentication

I'm using CakePHP 3.8 and migrating to the Authentication Plugin (https://book.cakephp.org/authentication/1.1/en/index.html).
When calling $this->Authentication->getIdentity()->getOriginalData() in a controller, I'd like to access a couple of assocations of my User entity.
At the moment, I'm doing this by implementing the following IdentityInterface method in my User entity:
public function getOriginalData() {
$table = TableRegistry::getTableLocator()->get($this->getSource());
$table->loadInto($this, ['Activities', 'Clients']);
return $this;
}
But I feel there should be a contain parameter somewhere within the Plugin configuration (as there was with the AuthComponent).
Can anyone guide me on how to include assocations on the User entity when calling getIdentity()?

The contain option of the authentication objects for the old Auth component has been deprecated quite some time ago, and the recommended method is to use a custom finder, and that's also how it's done in the new authentication plugin.
The ORM resolver takes a finder option, and it has to be configured via the used identifier, which in your case is probably the password identifier, ie something like:
$service->loadIdentifier('Authentication.Password', [
// ...
'resolver' => [
'className' => 'Authentication.Orm',
'finder' => 'authenticatedUser' // <<< there it goes
],
]);
In the finder method in your table class (probably UsersTable) you can then contain whatever you need:
public function findAuthenticatedUser(\Cake\ORM\Query $query, array $options)
{
return $query->contain(['Activities', 'Clients']);
}

Dynamically adding policy claims for Blazor authorization

I am creating an authentication and authorization handler for internal authorization purposes. My intention is to make it easy for my colleagues to implement the solution into their own projects. We are using Azure AD for authentication, and for authorization we are using Azure Groups. In order to do that, I feel like I am stuck on figuring out how to add authorization policies in an efficient way.
Right now I'm adding it through the officially described way in the Program class of my Client project in a Blazor webassembly hosted configuration:
builder.Services.AddAuthorizationCore(options =>
options.AddPolicy("PolicyName", policy =>
{
policy.RequireClaim("ClaimType", "ClaimValue");
})
);
This works fine, but it's not intuitive, as any given project could require several different policies
I have also added a custom Authorization Policy Provider, as described in this documentation from Microsoft:
https://learn.microsoft.com/en-us/aspnet/core/security/authorization/iauthorizationpolicyprovider?view=aspnetcore-6.0
I figured this would be what I was looking for, based on their description for this documentation, especially the first couple of lines in the documentation. But I still can't seem to get it to work as intended, without specifically adding each policy manually.
If need be I can show my custom implementation of the Authorization Policy Provider, but it is pretty much exactly as seen in the Github for the documentation.
Policies are most commonly registered at application startup in the Startup classes ConfigureServices method.
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthorization(config =>
{
config.AddPolicy("IsDeveloper", policy => policy.RequireClaim("IsDeveloper","true"));
});
}
the policy IsDeveloper requires that a user have the claim IsDeveloper with a value of true.
Roles you can apply policies via the Authorize attribute.
[Route("api/[controller]")]
[ApiController]
public class SystemController
{
[Authorize(Policy = “IsDeveloper”)]
public IActionResult LoadDebugInfo()
{
// ...
}
}
Blazors directives and components also work with policies.
#page "/debug"
#attribute [Authorize(Policy = "IsDeveloper")]
< AuthorizeView Policy="IsDeveloper">
< p>You can only see this if you satisfy the IsDeveloper policy.< /p>
< /AuthorizeView>
Easier Management
With role-based auth, if we had a couple of roles which were allowed access to protected resources - let’s say admin and moderator. We would need to go to every area they were permitted access and add an Authorize attribute.
[Authorize(Roles = "admin,moderator")]
This doesn’t seem too bad initially, but what if a new requirement comes in and a third role, superuser, needs the same access? We now need to go round every area and update all of the roles. With policy-based auth we can avoid this.
We can define a policy in a single place and then apply it once to all the resources which require it. Then when extra roles need to be added, we can just update the policy from the central point without the need to update the individual resources.
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthorization(config =>
{
config.AddPolicy("IsAdmin", policy => policy.RequireRole("admin", "moderator", "superuser"));
});
}
[Authorize(Policy = "IsAdmin")]
Creating shared policies
We need to install the Microsoft.AspNetCore.Authorization package from NuGet in order to do this.
After that create a new class called Policies with the following code.
public static class Policies
{
public const string IsAdmin = "IsAdmin";
public const string IsUser = "IsUser";
public static AuthorizationPolicy IsAdminPolicy()
{
return new AuthorizationPolicyBuilder().RequireAuthenticatedUser()
.RequireRole("Admin")
.Build();
}
public static AuthorizationPolicy IsUserPolicy()
{
return new AuthorizationPolicyBuilder().RequireAuthenticatedUser()
.RequireRole("User")
.Build();
}
}
Here we’re using the AuthorizationPolicyBuilder to define each policy, both require the user to be authenticated then be in either the Admin role or User role, depending on the policy.
Configuring the server
Rregistering the policies in ConfigureServices in the Startup class. Add the following code under the existing call to AddAuthentication.
services.AddAuthorization(config =>
{
config.AddPolicy(Policies.IsAdmin, Policies.IsAdminPolicy());
config.AddPolicy(Policies.IsUser, Policies.IsUserPolicy());
});
registering each policy and using the constants we defined in the Policies class to declare their names, which saves using magic strings.
If we move over to the SampleDataController we can update the Authorize attribute to use the new IsAdmin policy instead of the old role.
[Authorize(Policy = Policies.IsAdmin)]
[Route("api/[controller]")]
public class SampleDataController : Controller
Again, we can use our name constant to avoid the magic strings.
Configuring the client
Our server is now using the new policies we defined, all that’s left to do is to swap over our Blazor client to use them as well.
As with the server we’ll start by registering the policies in ConfigureServices in the Startup class. We already have a call to AddAuthorizationCore so we just need to update it.
services.AddAuthorizationCore(config =>
{
config.AddPolicy(Policies.IsAdmin, Policies.IsAdminPolicy());
config.AddPolicy(Policies.IsUser, Policies.IsUserPolicy());
});
In Index.razor, update the AuthorizeView component to use policies - still avoiding the magic strings.
< AuthorizeView Policy="#Policies.IsUser">
< p>You can only see this if you satisfy the IsUser policy.< /p>
< /AuthorizeView>
< AuthorizeView Policy="#Policies.IsAdmin">
< p>You can only see this if you satisfy the IsAdmin policy.< /p>
< /AuthorizeView>
Finally, update FetchData.razors Authorize attribute.
#attribute [Authorize(Policy = Policies.IsAdmin)]

Laravel 8 Jetstream: unable to login with the account seeded using factories and seeder

I am working on a Laravel 8 project. I have noticed that a couple of things have changed including authentication. I am using Jetstream for authentication.
I have installed the Jetstream and I can register and login going to the route /register and /login on the browser. What I am doing now is that for local development, I am creating seeder class so that I can seed the users and log in using those seeded users for local development. But when I log in using those account, it is always complaining that "These credentials do not match our records.".
This is what I have done. I have registered an account on browser using password, "Testing1234". The password hash is saved in the users table. I copied the password and use it in the UserFactory class as follow.
<?php
namespace Database\Factories;
use App\Models\Role;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Str;
class UserFactory extends Factory
{
use WithFaker;
/**
* The name of the factory's corresponding model.
*
* #var string
*/
protected $model = User::class;
/**
* Define the model's default state.
*
* #return array
*/
public function definition()
{
return [
'name' => $this->faker->name,
'email' => $this->faker->unique()->safeEmail,
'email_verified_at' => now(),
'password' => '$2y$10$tive4vPDzIq02SVERWxkYOAeXeaToAv57KQeF1kXXU7nogh60fYO2', //Testing.1234
'remember_token' => Str::random(10),
];
}
}
Then I created a user using factory as follow.
User::factory()->create(['email' => 'testing#gmail.com']);
Then I tried to log in using the user I just created. But it is always complaining, "These credentials do not match our records.". I cannot use the other passwords too. Even the default password that comes with the default user factory class. What is wrong with my code and how can I fix it?
Try using
User::factory()->make([
'email' => 'testing#gmail.com',
]);
I have finally found the issue.
In the JetstreamServiceProvider class, I have added the following code to customise the login flow.
Fortify::authenticateUsing(function (Request $request) {
});
My bad. That is what makes it failing.

Using CakePHP Form and Basic Authentication together

I've created a simple test site using CakePHP 3.8 and Authentication 1.0 to try it out. I'd like to use both Form and Basic authentication since the intended app will offer REST calls.
The site works properly if the HttpBasic is not included, that is the Login window is displayed. However, with HttpBasic, the site goes directly to basic authentication.
The code is directly from the cookbook.
What am I missing?
public function getAuthenticationService(ServerRequestInterface $request, ResponseInterface $response)
{
$service = new AuthenticationService();
$service->setConfig([
'unauthenticatedRedirect' => '/users/login',
'queryParam' => 'redirect'
]);
$fields = [
'username' => 'user',
'password' => 'password',
];
// Load Identifiers
$service->loadIdentifier('Authentication.Password', compact('fields'));
// Load the authenticators
$service->loadAuthenticator('Authentication.Session');
$service->loadAuthenticator('Authentication.Form', [
'fields' => $fields,
'loginUrl' => '/users/login',
]);
$service->loadAuthenticator('Authentication.HttpBasic');
return $service;
}
As mentioned in the comments, using the form authenticator and the HTTP basic authenticator together won't work overly well, this is due to the fact that the authentication service won't stop executing all loaded authenticators, unless one of them returns a response that indicates successful authentication.
This means that you'd always be presented with the authentication challenge response, and never see your login form. Only the actual authentication part would work in that constellation, ie directly sending your login credentials as form data to the login endpoint.
If you don't actually need the basic auth challenge response that is preventing you from accessing the login form, then you could use a custom/extended authenticator that doesn't cause a challenge response to be returned, which should be as simple as overriding \Authentication\Authenticator\HttpBasicAuthenticator::unauthorizedChallenge():
src/Authenticator/ChallengelessHttpBasicAuthenticator.php
namespace App\Authenticator;
use Authentication\Authenticator\HttpBasicAuthenticator;
use Psr\Http\Message\ServerRequestInterface;
class ChallengelessHttpBasicAuthenticator extends HttpBasicAuthenticator
{
public function unauthorizedChallenge(ServerRequestInterface $request)
{
// noop
}
}
$service->loadAuthenticator(\App\Authenticator\ChallengelessHttpBasicAuthenticator::class);
Also not that you might need to add additional checks in case your application uses the authentication component's setIdentity() method, which would cause the identity to be persisted in the session, even when using stateless authenticators. If you don't want that, then you'd need to test whether the successful authenticator is stateless before setting the identity:
$provider = $this->Authentication->getAuthenticationService()->getAuthenticationProvider();
if (!($provider instanceof \Authentication\Authenticator\StatelessInterface))
{
$this->Authentication->setIdentity(/* ... */);
}

How to allow to unauthenticated users see some specific pages or actions pages in Cake PHP 3?

With CakePHP 3 we used Auth component and this worked like this CakePHP - How to allow unauthenticated access to specific pages
Now I'm trying to use the new Authentication and Authorization plugins instead (I don't know if it is the best solution).
I have this case:
I have some tables in the database for entities (cars, brands, and users). I have users and 4 level user roles (pyramid).
- Admins can change everything
- Editors can see and add brands and cars, but only can edit or update cars and brands created by themselves.
- Registered users can add only cars and edit their cars (and see all cars and brands).
- Anonymous users can see all but only can create a user account.
Authentication works well alone. To allow anonymous user access to content I use $this->Authentication->allowUnauthenticated(['login', 'add']); but when I load Authorization plugin, everything give error.
Do I need to specify all Authorization access with authorizeModel and other functions? There is a way to authorize at the same time with both plugins? Do I really need Authorization plugin for this and is recommended or Authentication plugin can handle this?
With previous Auth component I worked with something like this piece of code:
In AppController.php
public function beforeFilter(Event $event)
{
$this->Auth->allow(['view', 'display']);
}
public function isAuthorized($user)
{
return true;
}
In UsersController.php
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
$this->Auth->allow('add', 'logout');
}
In Cars and Brands controllers
public function isAuthorized($user)
{
if (isset($authUser['role']) && $authUser['role'] === 'admin') {
return true;
}
if ($this->request->action === 'add') {
return true;
}
if ($this->request->action === 'index') {
return true;
}
if (in_array($this->request->action, ['edit'])) {
$carId = (int)$this->request->params['pass'][0];
if ($this->Cars->exists(['id' => $carId, 'user_id' => $authUser['id']])) {
return true;
}
}
return false;
}
Followed from https://book.cakephp.org/3/es/tutorials-and-examples/blog-auth-example/auth.html
My versions are:
- CakePHP 3.8
- Authentication plugin 1.4
- Authorization plugin 1.3
Sorry if my question is a bit basic but documentation is not very clear with this. I can add more details if needed.
Edit: If I quit unauthenticatedRedirect I get:
No identity found. You can skip this check by configuring `requireIdentity` to be `false`.
Authentication\Authenticator\UnauthenticatedException
If I add requireItentity as false, in AppController
$this->loadComponent('Authentication.Authentication', [
'requireIdentity' => false
]);
I get (where / is the path, can be /cars /brands)
The request to `/` did not apply any authorization checks.
Authorization\Exception\AuthorizationRequiredException
If I use this in AppController (always Authentication before Authorization)
$this->loadComponent('Authentication.Authentication', [
'requireIdentity' => false
]);
$this->loadComponent('Authorization.Authorization', [
'skipAuthorization' => [
'login',
]
]);
and this in Application
$service->setConfig([
'unauthenticatedRedirect' => \Cake\Routing\Router::url('/users/login'),
'queryParam' => 'redirect',
]);
I send all users to login page but authorization checks error appears.
With $this->Authorization->skipAuthorization(); in beforeFilter() user can see the pages and works but I don't know if it is appropriated.
If I use this in any controller beforeFilter $this->Authorization->authorizeModel('index', 'add', 'display' ...);
I get
Policy for `App\Model\Table\CarsTable` has not been defined.
Authorization\Policy\Exception\MissingPolicyException
In home (or pages controller) I get
Policy for `Cake\ORM\Table` has not been defined.
Authorization\Policy\Exception\MissingPolicyException
Do I really need to create policies for each table? I think is more complex than previous Auth component or maybe I'm doing something wrong.

How do I access the oauth2 authenticated user in a Lumen controller?

I have followed this excellent tutorial Building a Web App with Lumen and OAuth2 for setting up OAuth2 and Lumen. Everything is working fine apart from now I want to access the currently authenticated user information/model.
My route correctly posts the supplied information after I have logged in and I can break with Netbeans inside the controller but I am not clear how to get the user from the underlying Auth framework. I have tried the three methods indicated here Authentication - Laravel but to no avail. The lumen logs shows:
==== routes.php ====
$app->group(['namespace' => 'App\Http\Controllers','prefix' => 'api', 'middleware' => 'oauth'], function($app)
{
$app->post('info', 'InfoController#send');
}
==== InfoController.php ====
namespace App\Http\Controllers;
// the controllers
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Contracts\Auth\Authenticatable;
class InfoController extends Controller{
/* /api/info methods */
public function send(Request $request){
// can iterate over the entire users table but I just
// want the current user (must be some method through
// the authentication stack)
$users = \App\Auth\User::all();
foreach ($users as $user) {
$name = $user->name;
$key = $user->getAuthIdentifier();
$pwd = $user->getAuthPassword();
}
// CODE GETS HERE BUT how to get the current user?
// Authenticated OK (request supplies "Access-Token: Bearer ...")
}
}
This is probably not the cleanest solution and may not match your requirements exactly but it does retrieve the user.
I decided to make another DB query in the proxy to get the user with the same key (in my case, email address) that was requested by the client.
In my case I was sending the user id along with the standard oauth token.
You could use the same technique to set some value in the session.
// ../app/Auth/Proxy.php
namespace App\Auth;
use App\User; // ----- added this line
use GuzzleHttp\Client;
class Proxy {
...
private function proxy($grantType, array $data = [])
{
...
$response = json_decode($guzzleResponse->getBody());
if (property_exists($response, "access_token")) {
...
// added the following line to get the user
$user = User::where('email',$data['username'])->get()->first();
// untested, but you could add the user to your session here
$request = app()->make('request');
$request->session()->put('current_user', $user);
$response = [
'accessToken' => $response->access_token,
'accessTokenExpiration' => $response->expires_in,
'userId' => $user->id,
];
}
...
