Setting up SSO with an external OpenID authentication server

This document describes the operation and configuration of BlueMind with an external OpenID authentication server.

Prerequisites​

  • Have an OpenID server up and running
  • Have authorized the BlueMind authentication client with the OpenID server.
See, for example: Configuring an OpenID client for BlueMind with a third-party Keycloak

After configuration, note the following information, which will be used to configure BlueMind:

  • third-party OpenID server URL
  • OpenId client identifier (sometimes called Application ID)
  • **OpenId customer secret

How OpenID authentication works​

For initial authentication :

  1. The user tries to connect to BlueMind, which he opens in his browser.
  2. As it has not yet been authenticated, the BlueMind server redirects it to the OpenID server for authentication.
  3. Once authenticated, an openID cookie is placed in the user's browser, and the user is redirected to BlueMind with a ticket to validate.
  4. The BlueMind server :
    1. sees this ticket,
    2. asks the openID server if it is valid,
    3. si c'est bien le cas, autorise la connection et pose un cookie BlueMind dans le navigateur.

On next authentication:

  1. The customer requests access to the BlueMind server again.
  2. As it has the BlueMind cookie, it is automatically authenticated as long as this cookie is valid.

Configuration​

  1. In the administration console, go to System management > Supervised domains > choose domain > Security tab.

    ℹ️ Compte administrateur
    La procédure concerne la configuration du domaine, il est donc possible et préférable d'utiliser un compte administrateur de domaine plutôt que le superutilisateur admin0.

  2. Sélectionner le mode d'authentification OpenID dans le menu déroulant et renseigner les champs associés :

    • third-party OpenID server URL: indicate the URL of the OpenID server used to retrieve the list of endpoints.
      Par exemple, sur Keycloak, c'est une URL de la forme : https://{openid-server}/realms/{realm}/.well-known/openid-configuration
      Remplacer:
      • {openid-server}by OpenID server hostname
      • {realm} by the realm configured on the server
    • OpenId customer identifier
    • **OpenId customer secret

  3. Click on "Save" to save your changes.

Users will then be automatically redirected to the OpenID server when accessing the authentication page.
