spring-oauth | An example of using Oauth2 with Spring Security | OAuth library

I was following this guide which mentions that the @EnableAuthorizationServer is deprecated. But when I created a project with the following dependencies, I am not getting the deprecated messages. Is there something I am missing here.

Depedencies - Output from mvn dependency:tree

I am using the following and using following libraries:

spring-boot : 1.5.4

spring-security - 3.2.7

spring-oauth : 2.0.7

spring-boot-starter-data-mongodb : 1.5.4

spring-data-mongodb : 1.10.4

When I try get oauthtoken using this POST url: http://localhost:8080/oauth/token?grant_type=password&username=abc&password=xyz&client_id=testing&client_secret=testing using postman I get this error :

I am migrating from Spring Boot 1.4.9 to Spring Boot 2.0 and also to Spring Security 5 and I am trying to do authenticate via OAuth 2. But I am getting this error:

java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null

From the documentation of Spring Security 5, I get to know that storage format for password is changed.

In my current code I have created my password encoder bean as:

I have a setup of spring boot OAuth for AuthServer and it is resposible for serving a number of few resource server for authentication using spring-security-jwt. My problem is while authenticating I need to load the roles of a user but specific to the clientId. eg: If user1 have roles ROLE_A, ROLE_B for client1 and ROLE_C, ROLE_D for client2, then when the user logins either using client1 or client2 he is able to see all the four roles ie. ROLE_A, ROLE_B, ROLE_C, ROLE_D because I am getting roles based on username. If I need to have a role based on the client then I need clientId. FYI, I am using the authorization code flow for authentication. I have seen similar question but that is based on password grant but I am trying on authorization code flow and that solution doesn't work for me. Password grant question link

Below is my code where I need clientId
MyAuthenticationProvider.java

I am looking to use Spring Boot to create an OAuth2 Authentication server that could be used by multiple Resource server. Consequently, I am needing to create the two servers as independent apps. My primary references have been this article and this Stack Overflow question.

The referenced article combines both server types into a single app. I am having difficulty separating them.

I am able to retrieve a token using the following:

curl testjwtclientid:XY7kmzoNzl100@localhost:8080/oauth/token -d grant_type=password -d username=john.doe -d password=jwtpass

This call returns:

Our app is currently set up with OAuth OpenID connect authentication with an external (third-party) server. The requirement is to use user details service that loads the user from LDAP (along with the authorities/roles) to complete the authentication. So authentication.getPrincipal() should be returning the custom UserDetails object we use that gets generated by querying LDAP using the username obtained from the Open ID authentication.

I have tried the following:

• Followed Similar Issue but it seems like in the answer it's setting up the server-side and it doesn't work either
• Tried adding custom UserDetailsService in WebSecurityConfig

I m trying to have an OAuth2Client using authorization_code grant type, I can authorize the user and redirect the url, but when I try to access the resource using OAuth2RestTemplate, I get 401 UnAuthorized Is there something I need to do for the OAuth2RestTemplate to add the Authorization header ? I thought Spring-oauth2 will take care of adding the headers to OAuthRestTemplate by itself

Verified with TRACE logging as well

I've tried to add the users and authentication with OAuth. I followed by tutorial: Video Here is his source code: https://github.com/arocketman/Spring-oauth2-jpa-example

I've done exactly like him but my Intellij showed me some issuses.

I had to change my pom.xml from

I am attempting to build a Spring application that uses JWT tokens and the OAuth2 protocol. I have the Authentication Server running thanks to this tutorial. However, I am struggling with getting the Resource Server to function properly. From following the article, and thanks to a response to a prior question, this is my current attempt:

Security config for Resource Server:
