Login, Distributed SSO, Distributed Logout, and OAuth Token Grant Examples

The following examples requires Wildfly 8.0.0, JBoss EAP 6.x, or JBoss AS 7.1.1. Here's the highlights of the examples

• Delegating authentication of a web app to the remote authentication server via OAuth 2 protocols
• Distributed Single-Sign-On and Single-Logout
• Transferring identity and role mappings via a special bearer token (Skeleton Key Token).
• Bearer token authentication and authorization of JAX-RS services
• Obtaining bearer tokens via the OAuth2 protocol
• Interact with the Keycloak Admin REST Api

There are multiple WAR projects. These will all run on the same WildFly instance, but pretend each one is running on a different machine on the network or Internet.

• customer-app A WAR application that does remote login using OAuth2 browser redirects with the auth server
• customer-app-js A pure HTML/Javascript application that does remote login using OAuth2 browser redirects with the auth server
• customer-app-cli A pure CLI application that does remote login using OAuth2 browser redirects with the auth server
• product-app A WAR application that does remote login using OAuth2 browser redirects with the auth server
• admin-access-app A WAR application that does remote REST login to admin console to obtain a list of realm roles from Admin REST API
• database-service JAX-RS services authenticated by bearer tokens only. The customer and product app invoke on it to get data
• third-party Simple WAR that obtain a bearer token using OAuth2 using browser redirects to the auth-server.
• third-party-cdi Simple CDI/JSF WAR that obtain a bearer token using OAuth2 using browser redirects to the auth-server.

The UI of each of these applications is very crude and exists just to show our OAuth2 implementation in action.

This demo is meant to run on the same server instance as the Keycloak Server!

Step 1: Make sure you've set up the Keycloak Server

The Keycloak Appliance Distribution comes with a preconfigured Keycloak server (based on Wildfly). You can use it out of the box to run these demos. So, if you're using this, you can head to Step 2.

Alternatively, you can install the Keycloak Server onto any JBoss AS 7.1.1, EAP 6.x, or Wildfly 8.x server, but there is a few steps you must follow.

Obtain latest keycloak-war-dist-all.zip. This distro is used to install Keycloak onto an existing JBoss installation. This installs the server.

$ cd ${wildfly.jboss.home}/standalone
$ cp -r ${keycloak-war-dist-all}/deployments .

To be able to run the demos you also need to install the Keycloak client adapter. For Wildfly:

$ cd ${wildfly.home}
$ unzip ${keycloak-war-dist-all}/adapters/keycloak-wildfly-adapter-dist.zip

For JBoss EAP 6.x

$ cd ${eap.home}
$ unzip ${keycloak-war-dist-all}/adapters/keycloak-eap6-adapter-dist.zip

For JBoss AS 7.1.1:

$ cd ${as7.home}
$ unzip ${keycloak-war-dist-all}/adapters/keycloak-as7-adapter-dist.zip

Unzipping the adapter ZIP only installs the JAR files. You must also add the Keycloak Subsystem to the server's configuration (standalone/configuration/standalone.xml).

For Wildfly:

<server xmlns="urn:jboss:domain:1.4">

    <extensions>
        <extension module="org.keycloak.keycloak-wildfly-subsystem"/>
        ...
    </extensions>

    <profile>
        <subsystem xmlns="urn:jboss:domain:keycloak:1.0"/>
        ...
    </profile>

For JBoss 7.1.1 and EAP 6.x:

<server xmlns="urn:jboss:domain:1.4">

    <extensions>
        <extension module="org.keycloak.keycloak-as7-subsystem"/>
        ...
    </extensions>

    <profile>
        <subsystem xmlns="urn:jboss:domain:keycloak:1.0"/>
        ...
    </profile>

Step 2: Boot Keycloak Server

Where you go to start up the Keycloak Server depends on which distro you installed.

From appliance:

$ cd keycloak/bin
$ ./standalone.sh

From existing Wildfly/EAP6/AS7 distro

$ cd ${wildfly.jboss.home}/bin
$ ./standalone.sh

Step 3: Import the Test Realm

Next thing you have to do is import the test realm for the demo. Clicking on the below link will bring you to the create realm page in the Admin UI. The username/password is admin/admin to login in. Keycloak will ask you to create a new admin password before you can go to the create realm page.

http://localhost:8080/auth/admin/index.html#/create/realm

Import the testrealm.json file that is in the preconfigured-demo/ example directory.

Step 4: Build and deploy

next you must build and deploy

cd preconfigured-demo
mvn clean install

On EAP6/AS7 run:

mvn jboss-as:deploy

Or for WildFly run:

mvn wildfly:deploy

Step 5: Login and Observe Apps

Try going to the customer app and view customer data:

http://localhost:8080/customer-portal/customers/view.jsp

This should take you to the auth-server login screen. Enter username: bburke@redhat.com and password: password.

If you click on the products link, you'll be taken to the products app and show a product listing. The redirects are still happening, but the auth-server knows you are already logged in so the login is bypassed.

If you click on the logout link of either of the product or customer app, you'll be logged out of all the applications.

If you click on http://localhost:8080/customer-portal-js you can invoke on the pure HTML/Javascript application.

Step 6: Traditional OAuth2 Example

The customer and product apps are logins. The third-party app is the traditional OAuth2 usecase of a client wanting to get permission to access a user's data. To run this example open

http://localhost:8080/oauth-client

If you are already logged in, you will not be asked for a username and password, but you will be redirected to an oauth grant page. This page asks you if you want to grant certain permissions to the third-part app.

Step 7: Try the CLI Example

To try the CLI example run the following commands:

$ cd customer-app-cli $ mvn exec:java

This will open a shell that lets you specify a few different commands. For example type 'login' and press enter to login. Pressing enter with a blank line will display the available commands.

The CLI example has two alternative methods for login. When a browser is available the CLI opens the login form in a browser, and will automatically retrieve the return code by starting a temporary web server on a free port. If a browser is not available the URL to login is displayed on the CLI. The user can copy this URL to another computer that has a browser available. The code is displayed to the user after login and the user has to copy this code back to the application.

Step 8: Admin REST API

Keycloak has a Admin REST API. This example shows an application making a remove direct login to Keycloak to obtain a token then using that token to access the Admin REST API.

http://localhost:8080/admin-access

If you are already logged in, you will not be asked for a username and password, but you will be redirected to an oauth grant page. This page asks you if you want to grant certain permissions to the third-part app.
