The OAuth 2.0 authorization framework is a protocol that allows a user to grant a third-party website or application access to the user's protected resources, without necessarily revealing their long-term credentials or even their identity.
We will implement Authorization Server, Resource Server, and Client as part of this Tutorial to Completely understand the OAuth2.0 Flow and implement it with Spring Security and Spring Boot.

[@Max-zf5ot]

IMO video covers lot of content but from very high level perspective. May be this video should be a part of a course on Spring security where it would be easy to tie things together. Even if we exclude Spring security part, oauth/openId API flows are not highlighted to make things stand out right. I would suggest to invest time in this only if you know oauth2/openId connect and Spring security beforehand and just need a quick refresher.

Great video 😊 I request you to please make video on Spring Security with JWT token with role based access.

[@rexsam3134]

Client can be any user accessing the app. Can you elaborate on the User Resource Owner who is providing all details? As it's slightly tricky here as I am assuming Resource can be any URL endpoint within the application or microservice that the user wish to access. For all clients or users accessing the application, only one client ID will be used? Since you have demonstrated one unique client ID for OAuth. Is Bearer token created seperately for each client user accessing the application?

[@tobi061]

friends, 1. Authenticate and get token from one microservice 2. Then u can use that token for further requests either they are in the same microservice or different one 3. You just need to validate the token, get user details and set the security context holder This is basically a fliter for validating token does it make sense??

[@repotek]

I think you need to implement the same but with client credentials grant type. read more about it, this where you don't have user or UI involved but many backend microservice needs to share data between eachother

Thanks for the video! I will watch on this week. Say, with this implementation I can generate a bearer token in a server to use to access an application? Do you have any video showing how to use it?

[@cloudstackz]

This is what the Resource Server does for you automatically. If you want to manually authenticate against the Authorization Server (regardless you're using Java/Spring or not), you will have to implement the following steps: 1- Generate the authorization request with all the Client registration details (client_id, state, grant_type, etc.) 2- Create an endpoint in your app where you can receive the code grant. 3- Get the token by making another request against /token endpoint on the authorization server (using the same above details,, in addition to the code you received in the second step and client_secret).

[@tommy--k]

Since you are running the oauth-authorization-server and spring-security-client (separate) applications on the same database, isn't there a possibility that they can be out of sync since both apps are using separate connection pools, caches, etc ??? How would this be solved? Thanks for your insight on this!

[@milandol321]

I'm very curious as well, do you have an answer already?

[@cloudstackz]

They should be separate apps on different deployments. He used the same DB to simplify the demo for us instead of having multiple schemas and DBs to connect to.

[@pradeepns9052]

Hi.. Looking for suggestions on implementing security on spring-boot microservices integrated with angular UI. I have an external identity provider(Ping Federate) to support SSO and all user roles/authorities are maintained in the application database. What is the best approach to secure APIs? If Oauth is recommended way, how to implement it(Stateless). Should the Authorization Server be customized to connect to the identity provider Authorization Server and generate tokens from the custom Authorization Server? or Oauth2 client should generate tokens by loading user details from the database after successful authentication with the identity provider? Any code samples along with suggestions will be appreciated.

[@cloudstackz]

You don't need the Client app in your case, since you already have an Angular app (which will be the client). I think you need to add another AuthenticationProvider in your spring settings and add it to the current AuthenticationManager (where authentication happens against Ping Federate). This is a general idea of the implementation, let me know how it goes with you!

To block stateless tokens (like Opaque or JWT tokens), you will need to check against some cache or endpoint, where you listed that token as banned.

@@cloudstackz do you have any example (repository) to how do ir? Thanks

[@cloudstackz]

@@ricanmalra No standard implementation for that. It's like you look up the userId in your DB or get some cached value in your cache. Do what you see fit in your specific situation to ban and find banned tokens.
