I am building a Spring Boot application with Vaadin as front end. The application uses a third party library to authenticate the user with his identity card via SAML.
After this authentication the user is redirected back to my service and I can fetch the authentication result and optional attributes.
My question is, how can I implement the protection of specific Vaadin views within my application based on the authentication via the user's ID card and how do I set the user as authenticated appropriately?
I am new to Spring Security and the majority of its examples shows authentication via a login form with username and password which does not fit in this case.
You can find two approaches to secure your Spring Vaadin Application with either filter based (so only Spring Security) security, or a hybrid approach in this Github repository: https://github.com/peholmst/SpringSecurityDemo
You can also find blogposts about both approaches here:
Filter Based Security
Hybrid Approach
For you especially the Filter based approach could be interesting. You could implement a Filter checking the token (or whatever) you get from your login server and then allow/deny certain pages on your server for certain roles.

I wrote a spring boot webapp with spring security authentication over jpa. It uses jwt to grant access to a simple html/js application.
I'd like to add oauth2 flow in order to allow users to authenticate over github or google or whatever cloud system.
What kind of solution may I adopt to target it?
I see many applications like udemy, for example, or others. They allow multiple authentication types:
username and password
google account
facebook account
How may I replicate this behaviour in my webapp?
I've written a software system that uses Spring Cloud Netflix. Due to Spring Security 5 not offering support for writing an Authorization Server (pls shout out here https://github.com/spring-projects/spring-security/issues/6320) I need to write my own Authorization server. I want my application to permit Social login and username/password registration, have a custom login page but also use keycloack. I don't even know from where to start, if you have any documentations or code samples please provide.
You can use the cas project. By using the overlay it is easy to set up and to customize:
https://github.com/apereo/cas-overlay-template/blob/master/README.md
It serves a frontend where your user can be redirected to and can login. After successful login, the user is redirected back to your web page. The frontend is completely customizable.
It supports all kinda of authentication providers like keycloak, database or Google/Facebook.
After basic setup you just add the dependency inside the gradle file, configure your keycloak/database/... in the application.properties and can start using it as authentication server.
It fits perfect into a microservice landscape and is curated by professionals implementing security best practice.

I have a complex situation where I need to implement a security for web app on tomcat 8 that serve both static html and rest services. the app is spring mvc application (no spring boot)
the authntication ( sso ) process will go as follow:
if user jwt not exist in http header then authonticate with ldap, getting user authorities from db and create jwt back to user.
if jwt exist in header, skip ldap filtering , extract the user authorities from token.
I was thinking of first servlet filter that uses spnego library and get the windows domain name (user name to use in ldap) that filter will also check to see if ldap authontication is needed ( if token not provided) and pass it back to spring filter chine through http params..
I'm struggling to implement he ideal.
please help.
thanks
As I know, there is support for LDAP in spring security, might be it will help you.
Other than that, if you want to write your own filters then you have to add those in spring security filter chain.
I am developing a RESTful web service as a back-end layer for mobile application. This service receives combination of device id (as user id) an a pin (as password), and passes to another back-end service, that validates and returns the status of successful login along the user information, in case, the user is authorized. My service is not validating the user. And mobile sends sub sequent requests to my RESTful service.
So, please suggest, how can I make all this system(especially the RESTful) secured, using Spring security.
I am using a Tomcat server, Spring and Jersey
I recently implemented a method to secure my existing RESTful APIs in Spring. I have used a token based authentication model using OAuth2. In my project, I wanted to secure my API's in a way that every request is individually authenticated and authorised based on the token present in the header. If this is something you are looking for, then I would highly recommend you to take a look at the documentation here. If there is anything you are stuck at while implementing it. Please do let me know.
Also, you can find multiple projects for Spring and OAuth here
I am trying to build an application where login is done by siteminder SSO. Once login is done I need to get the user info(like roles,permissions) for logged in user from LDAP and put in session.
Aslo I am using spring MVC to expose REST services. I want my rest services to be accessible only for certain roles(Like Manager/Admin etc). Also UI will display/hide pages based roles.
I want to know what is the best approach to achieve the above.
Please note I am using spring MVC on WAS7.
