Introduction

Keycloak is an open source identity and access management platform, and it provides support for standard protocols like OpenID Connect, OAuth 2.0, and SAML.

In this tutorial, SAML will be used in Keycloak to enable Single Sign-On (SSO) capability with Joget.

This tutorial serves only as a general guide, using minimal-required configurations on Keycloak to enable SSO via SAML protocol with Joget.

To use Keycloak in a production environment, please see Configuring Keycloak for production or other relevant Keycloak guides.

Prerequisites

  • Joget server
  • Docker

Tutorial Steps

1. Keycloak Installation

To quickly get started on Keycloak and for ease of testing, we recommend installing Keycloak via Docker in your local development environment.
Do follow the guide until the part where you have successfully created a sample user in Keycloak & verify by logging in with this new user credentials in the Keycloak Account Console.

At this point of time after completing the Keycloak installation tutorial, you should have:

  • A separate realm called myrealm in Keycloak
  • A sample user created in Keycloak

    Tip

    If your Joget instance currently does not have a license, it is limited to free first 3 users only, sorted alphabetically. For ease of testing, you can create a sample user with username of cactus-jim for example.


Important Note

In this tutorial, it is presumed that the Keycloak instance will be running and exposed on the same host machine running your Joget instance. 

In this case, since the default bundled Tomcat server hosting the Joget platform operates on port 8080 by default, do ensure the deployed Keycloak container does not clash with the same host port.

For example, you can map Keycloak container to expose on host port 8500 or any other non-clashing port instead. 

2. Plugin Installation

  1. Download the SAML Directory Manager Plugin from the Joget Marketplace, and upload the plugin .jar file into your Joget instance.
    This plugin's source code is also available in JogetOSS Github. Projects under JogetOSS are community-driven and community-supported, and you are welcome to contribute to the projects.

  2. Then, in Admin Bar → Settings → General Settings → API IP Whitelist, do whitelist external IP addresses. For now, you can allow all public users (using * symbol to indicate "allow all").
    This is to allow end user browsers to communicate with the SAML plugin.


  3. Save the settings.

3. Plugin Configuration

  1. In Admin Bar → Settings → Directory Manager Settings → Select Plugin, select SAML Directory Manager to start configuring the plugin.
  2. Copy both values of Entity ID and ACS URL, and temporarily save these values in a convenient place for later use.
    These values are required in order to create a valid client in Keycloak.


  3. IDP Certificates need to be copied from the admin console of the keycloak.
    Open your KeyCloak admin console->Realm Settings ->Keys Tab -> Click on the Certificate RSA 256 Key.

Paste this value in the IDP Certificate field.

User Provisioning Enabled checkbox will allow Joget to authenticate users who are not in joget directory manager. It will also create an account in joget. 

Configure other settings as per your industry requirements. 

4. KeyCloak Configuration

Creating a client in Keycloak will enable the SSO from the keycloak application. 

Open the Keycloak admin console -> Clients-> Create 



Please use the following configurations:

Client ID: SAML JOGET API URL
Name: Optional 

Description: Optional 

Enabled: ON

Consent Required: OFF

Login Theme: Optional 

Client Protocol: SAML

Include AuthnStatement: ON

Include OneTimeUse Condition : OFF

Sign Documents: OFF

Sign Assertions: ON

Signature Algorithm: RSA_SHA256

SAML Signature Key Name: CERT_SUBJECT

Canonicalization Method: EXCLUSIVE

Encrypt Assertions: OFF

Client Signature Required: OFF

Force POST Binding: OFF

Front Channel Logout: OFF

Force Name ID Format: ON

Name ID Format: username

Root URL: EMPTY

Valid Redirect URIs: https://joget-Server-URL/jw 

Base URL: EMPTY

Master SAML Processing URL:   SAML JOGET API URL 

IDP Initiated SSO URL Name:  SAML JOGET API URL

To test configuration, you can copy the target IDP initiated SSO URL and paste it in incognito mode of browser and login to keycloak, If all is good you will be redirected to Joget home page with login.

The final configuration is the configure the fields.

Open the Mapper tab on the client configuration.  Add the Built-in mappings




You need to define the names for each option so joget will be able to handle the values

Mapping Name

SAML Attribute Name

X500 surname

User.LastName

X500 givenName

User.FirstName

X500 email

email

Optional Modifications

Addon SSO button on login page

You can also allow end users to SSO via Keycloak with a convenient button in your Joget login page.

Edit the App Center app, navigate to UI builder -> Settings -> Login Page UI --> Custom HTML (After Login Form), then paste in the code snippet below.

<div class="custom-logins" style="place-items: center; width: 100%;">
<hr>
<a href='{Your-target-IDP-initiated-SSO-URL}' class='btn' style="display: block; width: 100%;">Login with Keycloak</a>
</div>
<script>
$(document).ready(function() {
   const customLogins = $("div.custom-logins").detach();
   $('#loginForm table').after(customLogins);
});
</script>
