Benefits of Using OpenID Connect

Oct 13, 2025 by magicalceylontours.com 52 views

Introduction

In today's digital landscape, secure authentication is a top priority for any web application. One of the most widely used authentication protocols is OpenID Connect (OIDC), which provides a secure and standardized way to authenticate users. In this article, we will explore how to create an Elastic link that uses automatic OpenID Connect authentication for users not already authenticated.

What is OpenID Connect?

OpenID Connect is an authentication protocol that allows users to authenticate with an identity provider (IdP) and obtain an access token that can be used to access protected resources. OIDC is built on top of the OAuth 2.0 authorization framework and provides a simple and secure way to authenticate users.

Benefits of Using OpenID Connect

Using OpenID Connect provides several benefits, including:

Security: OIDC provides a secure way to authenticate users, reducing the risk of unauthorized access to your application.
Scalability: OIDC allows users to authenticate with any OIDC-compliant identity provider, making it easy to scale your application.
Flexibility: OIDC provides a flexible way to authenticate users, allowing you to choose the identity provider that best fits your needs.

How to Create an Elastic Link with Automatic OpenID Connect Authentication

To create an Elastic link with automatic OpenID Connect authentication, you will need to follow these steps:

Step 1: Configure OpenID Connect

To use OpenID Connect, you will need to configure it in your Elastic application. This involves setting up the OIDC provider, configuring the authentication flow, and setting up the client ID and secret.

Configure OIDC Provider

To configure the OIDC provider, you will need to set up the following:

Authorization endpoint: This is the endpoint where the user will be redirected to authenticate with the OIDC provider.
Token endpoint: This is the endpoint where the user will obtain an access token after authenticating with the OIDC provider.
User info endpoint: This is the endpoint where the user's profile information will be retrieved.

Configure Authentication Flow

To configure the authentication flow, you will need to set up the following:

Redirect URI: This is the URI that the user will be redirected to after authenticating with the OIDC provider.
Client ID: This is the ID of the client that will be used to authenticate with the OIDC provider.
Client secret: This is the secret key that will be used to authenticate with the OIDC provider.

Step 2: Create an Elastic Link with Automatic OpenID Connect Authentication

To create an Elastic link with automatic OpenID Connect authentication, you will need to use the following code:

@RestController
public class ElasticLinkController {
    
    @GetMapping("/elastic-link")
    public String getElasticLink() {
        // Get the current user's authentication status
        boolean isAuthenticated = SecurityContextHolder.getContext().getAuthentication() != null;
        
        // If the user is not authenticated, redirect to the OIDC authentication endpoint
        if (!isAuthenticated) {
            return "redirect:" + oidcProvider.getAuthorizationEndpoint() + "?client_id=" + clientId + "&redirect_uri=" + redirectUri;
        } else {
            // If the user is authenticated, redirect to the target page
            return "redirect:/target-page";
        }
    }
}

Step 3: Configure the CasController

To configure the CasController, you will need to set up the following:

Client ID: This is the ID of the client that will be used to authenticate with the OIDC provider.
Client secret: This is the secret key that will be used to authenticate with the OIDC provider.
Redirect URI: This is the URI that the user will be redirected to after authenticating with the OIDC provider.

@RestController
public class CasController {
    
    @GetMapping("/cas-link")
    public String getCasLink() {
        // Get the current user's authentication status
        boolean isAuthenticated = SecurityContextHolder.getContext().getAuthentication() != null;
        
        // If the user is not authenticated, redirect to the CAS authentication endpoint
        if (!isAuthenticated) {
            return "redirect:" + casProvider.getAuthorizationEndpoint() + "?client_id=" + clientId + "&redirect_uri=" + redirectUri;
        } else {
            // If the user is authenticated, redirect to the target page
            return "redirect:/target-page";
        }
    }
}

Conclusion

In this article, we have explored how to create an Elastic link that uses automatic OpenID Connect authentication for users not already authenticated. We have also discussed the benefits of using OpenID Connect and provided a step-by-step guide on how to configure it in your Elastic application. By following these steps, you can create a secure and scalable authentication system for your application.

Acceptance Criteria

To ensure that the Elastic link with automatic OpenID Connect authentication is working correctly, you can use the following acceptance criteria:

Access immediately the targeted page following the link with an authenticated session
Be redirected to the OpenID Connect authentication when accessing the link without being authenticated
Be redirected on the targeted page after authenticating on OpenID Connect
