Which version of Keycloak is supported on Ubuntu?

How to configure Keycloak for use with an Ubuntu-based application?

Keycloak is an open source Identity and Access Management solution that makes it easy to secure applications or microservices with little to no code. It can be used as an SSO solution for web applications, mobile applications, and RESTful web services.

To configure Keycloak for use with an Ubuntu-based application, you will need to install the Keycloak client on your Ubuntu server. The Keycloak client is a Java application that provides the functionality to authenticate with and communicate with a Keycloak server.

Once the Keycloak client is installed, you will need to create a client on the Keycloak server. This can be done through the Keycloak admin console. The client should be configured with the URL of your Ubuntu server.

Once the client is created, you will need to add a user to the client. This can also be done through the Keycloak admin console. The user should be assigned the role of “client”.

The next step is to add a filter to your application’s web.xml file. This filter will redirect unauthenticated requests to the Keycloak server for authentication. The filter should be configured with the URL of the Keycloak server and the name of the client.

Finally, you will need to add a realm to the Keycloak server. A realm is a collection of users, roles, and clients. The realm should be configured with the URL of your Ubuntu server.

Once these steps have been completed, Keycloak will be up and running and configured for use with your Ubuntu-based application.
