Seamlessly Integrate Keycloak SSO with Your WordPress Site

In today’s digital landscape, providing a secure and streamlined login experience is crucial for user satisfaction and site management. Single Sign-On (SSO) offers a robust solution, and when it comes to open-source identity and access management, Keycloak is a powerful choice. This guide will walk you through setting up Keycloak SSO for your WordPress site, allowing users to log in with their Keycloak credentials.

Getting Started: Plugin Installation

The first step is to integrate your WordPress site with Keycloak. This can be accomplished by using a dedicated plugin.

1. From your WordPress dashboard, navigate to Plugins and select Add New.youtube
2. Search for “WordPress OAuth single sign-on” to find the necessary tool.youtube
3. Install and activate the miniOrange OAuth Client Single Sign-On plugin.youtube

Configuring Keycloak as Your Identity Provider

With the plugin activated, it’s time to set up Keycloak to handle authentication requests.

Realm and User Setup

Within your Keycloak admin console, you’ll need to configure a realm, which is a space where you manage users, roles, and groups.

1. Create a new realm or select an existing one.youtube
2. Establish roles for your users to define their permissions.youtube
3. Add users to the realm and assign them a permanent password and the appropriate roles. You can also organize users into groups for easier management.youtube

Client Configuration

Next, you need to create a client in Keycloak that will represent your WordPress application.

1. In the Clients section, create a new client and set the client protocol to openid-connect.youtube
2. Change the access type to confidential to ensure secure communication.youtube
3. From the WordPress plugin, copy the callback URL and paste it into the Validate Redirect URI field in your Keycloak client settings.youtube

Connecting WordPress to Keycloak

Now, let’s configure the WordPress plugin to communicate with Keycloak.

1. Open the miniOrange OAuth Client plugin settings in WordPress and select Keycloak from the list of providers.youtube
2. You will need your Client ID, Client Secret, Keycloak domain, and realm name.youtube
3. Copy the Client ID from your Keycloak client settings and paste it into the corresponding field in the WordPress plugin.youtube
4. In Keycloak, go to the Credentials tab of your client to find and copy the Client Secret, then paste it into the plugin settings.youtube
5. Enter your Keycloak domain and realm name.youtube
6. Save the configuration and use the Test Configuration button to ensure a successful connection.youtube

Attribute Mapping and Final Touches

After a successful test, you can map user attributes from Keycloak to WordPress. This ensures that user information, such as usernames and emails, is correctly synchronized.

1. Navigate to the Attribute/Role Mapping tab in the plugin.youtube
2. Map the desired Keycloak attributes to the corresponding WordPress user fields.youtube
3. Finally, to make the SSO login accessible to your users, go to Appearance > Widgets in WordPress and add the miniOrange OAuth widget to your site.youtube

Once these steps are completed, users visiting your site will see a login button that redirects them to Keycloak for authentication. After entering their credentials, they will be seamlessly logged into your WordPress site, enjoying a secure and efficient user experience.
