Set up SSO authentication with Auth0#

#Objective

Is your company identity management handled on Auth0? If you want to use it to login to your Data Platform apps, this guide is for you.

Open the IAM and click on Auth. Provider.

If you haven't done so already, add a new Auth0 authentication provider on Data Platform. Else, just edit it.

The configuration is done in two parts. First you need to configure the rights on Auth0 and then configure the authentication provider in the Data Platform Identity Access Manager.

#Configuration on Auth0

You need to register Data Platform as an application on your Auth0 environment. Go there: https://manage.auth0.com/dashboard.

#Step 1. Register the Identity Access Manager on Auth0

You need to register an application inside of Auth0. This works with any app you would like to connect to Auth0 but in this case, you are going to register the Data Platform IAM directly.

In the sidebar, select Applications. Then click on Create application.

Select Regular Web Application.

Open the Settings of the newly created application.

#Callback URL

Scroll down to the Allowed Callback URLs section in the Settings page of the application.

In the URL field, copy and paste the Reply URL field in the new authentication provider you added on Data Platform (it is the same for the entire Data Platform IAM).

#Step 2. Retrieve the Domain

The Domain is the equivalent of your tenant id on Auth0. You can find it in the Settings of the application: look for the Domain section.

#Step 3. Retrieve the Client ID

The Client ID is specific to your application. You can find it in the Settings of the application: look for the Client ID section.

#Step 4. Retrieve the Client Secret

The Client Secret is specific to your application. You can find it in the Settings of the application: look for the Client Secret section.

#Summary

If you have properly followed all the previous steps, you should have this list of information.

Domain (Step 2): xxxxxxxxxx.auth0.com
Client ID (Step 3): XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Client Secret (Step 4): XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

#Configuration on the Platform Identity Access Manager

You now have to configure your new authentication provider in your Data Platform Identity Access Manager.

#Fill in the basic information

• Name / Description: This is the internal name and description for your new authentication method
• Directory: This is a unified tag for all accounts that will be created from this directory. For example, you can input Auth0
• Tags: This offers more tagging options. They are completely optional
• Reply URL: This is the Data Platform URL where your authentication provider redirects to
• Active: This specifies whether this authentication provider can be used to login or not

#Fill in Auth0 configuration

Now locate the Auth0 Configuration panel.

Fill in the information collected on Auth0 in the previous section, as such:

• Domain: Domain (retrieved in step 2 of the configuration on Auth0)
• Client ID: Client ID (retrieved in step 3 of the configuration on Auth0)
• Client Secret: Client Secret (retrieved in step 4 of the configuration on Auth0)
• Scope: This represents how much information Data Platform will be able to access from your Auth0. This field is optional: the default value is openid email profile

#Fill in the bindings rules

The Bindings panel allows you to customize the mapping of the fields between Auth0 and Data Platform.

Email, login, first and last name are mapped by default.

Bindings can be overriden if you need to save additional information from Auth0 into your Data Platform Identity Access Manager, like the job title.

The easiest way to configure bindings is to retrieve a response from a login of an user by following these steps:

1 - Do a sample login to any Data Platform application using your newly configured Auth0 authentication provider.
2 - Open the Log History page of the IAM authentication provider (here Auth0).

3 - Open the latest log: the original response from Auth0 will look like this:

{
  "given_name": "John",
  "family_name": "Smith",
  "nickname": "jsmith",
  "name": "John jsmith",
  "picture": "https://lh3.googleusercontent.com/a/AATXAJwHYHTaalrHB9puNg1bjfCuKIuZPqVFMUcma5e5=s96-c",
  "locale": "fr",
  "updated_at": "2021-10-01T15:14:35.524Z",
  "email": "jsmith@example.com",
  "email_verified": true,
  "iss": "https://dev-m4zopi2a.us.auth0.com/",
  "sub": "google-oauth2|112554878744",
  "aud": "****",
  "iat": 1633101540,
  "exp": 1633137540,
  "user": {
    "sub": "google-oauth2|112554878744",
    "given_name": "John",
    "family_name": "Smith",
    "nickname": "jsmith",
    "name": "John Smith",
    "picture": "https://lh3.googleusercontent.com/a/AATXAJwHYHTaalrHB9puNg1bjfCuKIuZPqVFMUcma5e5=s96-c",
    "locale": "fr",
    "updated_at": "2021-10-01T15:14:35.524Z",
    "email": "jsmith@example.com",
    "email_verified": true
  }
}

4 - On top of the default email, login, first and last name, any additional property from Auth0 can be saved as a custom configuration.XXX field on Data Platform by using the "JSON" mode.

For example, you can add a fullname property on Data Platform from the name field from Auth0:

{
  "login": "email",
  "email": "email",
  "pronoun": "",
  "firstname": "given_name",
  "lastname": "family_name",
  "configuration.fullname": "name"
}

#Custom mappings

The Custom mappings panel allows you to automatically assign all users logged in through this authentication provider to a role or a group.

Learn how to set up custom mappings.

#Set live

You are all set configuring your Auth0 connector! If you haven't done it already, click on Create - else make sure to Save.

In the Authentication Providers list, you now see your new method. Make sure you set it as active.

Make sure this new authentication method is visible for the applications of your choice. You should now see an Auth0 option on your application's login page. By clicking on it, you will be redirected to the Auth0 login screen, or directly into the app if you are already logged into your account.

Make Auth0 visible on your apps' login page
