EDIT: I already set up login form with symfony and the authorisation works just fine. But would like to go a bit deeper into how it is manage by the security bundle of symfony.
I want to study/understand the way symfony security handles authentification. If I understand well so far the URL "/login_path" as specified in security.yml at the line check_path trigger authentification in Symfony:
Then come controller/listener/service get username and password throught the variable POST["_username"] and POST["_password"] from the login_form.
I wanted to have a look how this is handled in Symfony. Which files should I have a look at in the Security folder in Symfony?
Anyone to just explain me the mecanism about how it works?
Does some listener catch the URL then transmit it to some controller in Symfony.
(I just want to have a look to understand it)
thanks in advance.
There is no Single file you can Look at. Security in Symfony is splitted into multiple aspects like authentication, authorization, user providers,..
Read the manual, it's explained there very well. But yes, it's really complex.
http://symfony.com/doc/current/book/security.html
The basic process looks like this:
- firewall rules decide if access is allowed and auth is required
- a token is generated by one of the configured listeners
- authentication provider validates the token
- user is loaded from configured user provider

I'm building a shop system at the moment. Using Symfony+CommerceTools as backend and Twig as frontend.
What I want to achive:
In store A, called with a.store.com, you should be always redirected to /login page if you arent logged in yet. This store can only be used when logged in.
In store B, called with store.com, you can access anything without being logged in.
Right now, anyone can access everything. Thats right for store B.
I could add a rule to the security.yaml, that redirects to /login if not logged in, that would work for store A.
But I need a solution, that have both. Depending on a variable in commerceTools.
So if you have logins set up this is quite straight forward using roles in Symfony. If you don't have a login form set up yet check out this Symfony login guide.
To use roles you will have to ensure you have your security system set up which is in this Symfony Security guide - Note this will need to be set up first if you intend to use the Symfony login forms I linked to first.
The bit you need in particular to restrict access to certain sections of your site is Section 4) Denying Access, Roles and other Authorization in the above guide.
Essentially in your User entity class you have roles set to your users. Then, my preferred way of securing certain parts of your site would be by adding role requirements into the controllers for the views you want to secure, for example:
// src/Controller/ShopAController.php
// ...
public function shopA(): Response
{
$this->denyAccessUnlessGranted('ROLE_USER');
}
You will notice when setting up the security system, that there are settings to give any registered users the role of ROLE_USER, so you can use this to secure parts of your site to only registered users, or you could create a new role such as ROLE_CUSTOMER or something.
If a none logged in user tries accessing this secured view, they will be redirected to the login page.
Then for the views of your site you want anyone to be able to access you simply don't set any role access rules in those controllers.
This avoids needing to add URL paths to your security.yaml as you wanted as well.
I hope this was helpful! Give it a try and follow the Symfony tutorials I linked, they're very easy to follow :)
So i have Symfony 4 app which should allow login via LDAP and based on your groups modify some of the values in this ldap directory.
The Login itselfs, and mapping from Ldap Groups to ROLE_ works perfectly.
The idea was that only the currently logedin user does a modification. Not a hidden Directory Admin.
For this i would need to $ldap->bind() with the user credentials each time a loged in user wants to modify the directory.
But for this i would need the password. The only way i could think of, would be to save the password in the session - but form a security standpoint this would be a very very bad idea.
Is there any other way? Like store the already binded connection somehow?
As far as I see in the Symfony security component - the UserProvider only refreshes the user from sesison - without calling ldap again.
The LdapBindAuthenticationProvider only uses the ->bind() call with the given credentials and catches an exception if password doesnt match.
But the connection itself is a simple fire & forget.
I was able to get the following sample code to work: https://spring.io/guides/tutorials/spring-boot-oauth2/. It works very well, however, it allows anyone with a Github credentials the ability to access my application!
What I'd like to do is extend the sample code's functionality to basically validate that the authenticated Oauth2 principal is also a previously registered user of the application. If they are not registered, they will be redirected to a registration screen.
I was thinking of utilizing a AuthenticationSuccessHandler to handle the registered user validation and perhaps invalidate their Github security token (somehow) if they are not a registered user. Am I going down the wrong path?
I will not post any of my code, because this is more just a question to know if it's possible.
I've been googling a lot, but didn't find any concrete solutions. I hope someone can help me here.
The facts:
I have a login form
I need to authenticate the credentials over a web-service
I need to send both username and password, to get back a token if logged in successfully.
The problems:
With a custom provider I'm always stuck with the fact that they only have direct access to the userename, like: loadUserByUsername. I need to access the password there as well, to be able to send this to my web-service.
I have only 1 web-service which sends only back a token if provided username and password are correct.
Question:
How can I access and send both username and password to my web-service?
Thanks!
Generally speaking one would authenticate using an API token to a web service.
That API token is usually issued via an auto-generation script when the user account is created (either by an admin or by a registration form). This token is then passed by the API call to the web-service in a header which then uses it to authenticate the user.
As far as Symfony goes, by far the easiest way of doing this is with Guard. A new component built by Ryan Weaver from KNP.
KNPUniversity has a great tutorial on it (for free).
Note that this is only one option of many, and the 'best' way is probably mainly opinion based and directly related to the use case in question. But it might help you get on the right track.
If the token you want to create should be a JSON Web Token (JWT), a very conventient bundle is LexikJWTAuthenticationBundle, which does almost all of the work automatically. If you just follow the documentation, you will have it quickly up and running. You can combine it with FOSUserBundle, with a custom User entity or whatever.
I am using HWIOAuthBundle with FOSUserBundle with success.
When I go to the /login page it redirects me to the Google Accounts, authorizes and returns back to the register form with filled data (except password fields).
Is it possible to auto register user with ommiting register form ?
In this case we do not need password because of authentication with Google Account.
How should I achieve this scenario ?
A question is a bit old, but better later than never.
You just need to create a custom provider - if you want to integrate the bundle with FOSUserBundle you need to override the FOSUBUserProvider class.
In HWIOAuthBundle/Security/Core/User directory you may find all providers that are available in the OAuthBundle out of the box.
To create new user while connecting you just need to override loadUserByOAuthUserResponse() method of the FOSUBUserProvider (or EntityUserProvider, etc.) provider class. As you may see, default method throws an exception if the user is not found in database, you just need it to call userManager and create new entry.
This is exactly the same situation as with FOSFacebookBundle intergration (if you did so).
Hopes this answer helps you (especially it may sound a bit chaotic).
Edit:
I've posted a blog post explaining the integration process.
Try this gist
or this tutorial
There's a good walk-through on how to integrate HWIOAuthBundle and FOSUserBundle to achieve the automatic user registration and update here, which might be worth a read:
https://gist.github.com/danvbe/4476697
Yes of course.
You should handle a response from google and authorize user manualy something like:
// authorize
$token = new OAuthToken(null, $user->getRoles());
$token->setUser($user);
$token->setAuthenticated(true);
// update session
$session = $this->getContainer()->get('session');
$session->set('_security_secured_area', serialize($token));
$session->save();
after user was authorized redirect to the call page by user
