Single Sign-On (SSO) is part of Advantech WISE-PaaS cloud solution and  plays an important role in the interoperability of Internet identity. It provides a central login mechanism.

OpenID Connect utilizes Keycloak which is an open source identity and access management for modern applications and services.

Features Overview

[Please describe]

• Single-Sign On : Login once to multiple applications

• Standard Protocols : OpenID Connect, OAuth 2.0 and SAML 2.0

• Centralized Management : For admins and users

• Adapters : Secure applications and services easily

• High Performance : Lightweight, fast and scalable

• Clustering : For scalability and availability

• Themes : Customize look and feel

• Extensible : Customize through code

• Password Policies : Customize password policies

API Protocol Flow

WISE-PaaS/Single Sign-On use the OAuth 2.0 protocol for authentication and authorization.

• User/Browser
• Application
• Authorize Server
• Resource Server

Here is a more detailed explanation of the steps in the diagram:

1. The application requests authorization to access service resources from the user
2. If the user authorized the request, the application receives an authorization grant
3. The application requests an access token from the authorization server (API) by presenting authentication of its own identity, and the authorization grant
4. If the application identity is authenticated and the authorization grant is valid, the authorization server (API) issues an access token to the application. Authorization is complete.
5. The application requests the resource from the resource server (API) and presents the access token for authentication
6. If the access token is valid, the resource server (API) serves the resource to the application

Implementation

Components

[Please describe]

• OpenID Connect Server
• OpenID Connect Client
• OAuth 2.0 Server
• OAuth 2.0 Client

Document

Apply a manager account for OpenID Central Server

Please sen a request to WISE-Paas/OpenID Connect service manager by E-mail. And provide the following information

• Service name : [RMM] as your realm.
• Client name : [RMMClient] a client definition for a app to login in.
• User registration : [True/False] Enable/Disable user registeration.
• Administrator account : [RMMAdmin] Use this account to manage this realm. The default password is same as account name. Change password after first login.

Setting your service on OpenID server

Open the https://openidserver.redirectme.net:8443/auth/admin and login with applied administrator account to config your realm before implement your client app.

• (Essential) Public key : OpenID server generate a unique key for client app identification. Copy the public key to json setting file include in the client app .

​

• (Essential) Valid Redirect URIs & Web Origins : Provide valid uri pattern for your client app. OpenID server would redirect to your client page while a successful login or logout. Your client page must be publicly accessible.

Click the "Client  ID" to setting page

• (Optional) User registration : Enable/Disable user self registration. If turn off, you would need to create accounts for login.

Implement client codes

1. Copy the json , html sample code to your local web site.
2. Modify json setting
3. Once the test HTML page is opened, it is automatically directed to OpenID Connect Server.
4. While login success, it will automatically lead back to test page.

Sample code

OpenID.json : Replace realm, realm-public-key, client-id, resource according to realm setting

{
  "realm": "RMM",
  "realm-public-key":"MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAgXyx5rl6laDJKt5vvz1lNYsrDgNHZKetagmr81IyvTuYpWQFwJwnai5pNQxfa6jgFBPiOg+pwD7jAfCgQghqWZFWVqPkL+Wt1PXEAXkg54yz9+oCrahsHZPoaQyWhTyf8StBqFUZurA7HkfRqPFINge5xo0jlkjVTcGUUTD/4HzEXc9tYdI1wqv9Ymd+eWG/uhYMu67DvzdNg/aIgxp5U7kYWZiyApjZH4ymP7fEWyFSSRSM/IwWKuW1Lc22w2nEU4RozZ5WF7QoOsjGB7ya62wwJN9UC+v+AgtUDy0VDkiDWruSz9pFQhTyWS1ITh9qoZerJdhu47eHPNKhoGVJpwIDAQAB",
