OIDC

Introduction

OpenID Connect (OIDC) is an identity protocol built on top of OAuth 2.0 that provides secure authentication and authorization. It allows users to securely log in to various services while service providers can simultaneously access verified identity information. The following article describes how to set up OpenID Connect (OIDC) in Relution using Microsoft Azure.

Settings in Relution

OIDC can be configured in the Relution portal under Settings > OpenID Connect. The following screenshots include a working configuration using Microsoft Azure.

Configuration details

Name of the provider: Will be displayed on the login button in the rleution portal
Create unknown users in Relution: Unknown users are created by login in Relution.

💡

If a login is done with an unknown user on the store orga with OIDC configured, it will be created in the store organization. In the case of multiple clients with OIDC configuration, the login must be made via the organization URL so that the unknown user is created in the corresponding organization. This URL is displayed in the portal in the OIDC connections.

Client Details

Client ID" Corresponds to the application ID in Azure.
Client Secret: Corresponds to the client secret key to the application ID in Azure.

Server URIs

Use Discovery Endpoint: If supported by the provider, an automatic configuration of the required URIs is performed.
Manual configuration of endpoints: Necessary as soon as automatic discovery does not work.

💡

If using Microsoft Azure, endpoints must be entered manually.

Authorization URI:
https://login.microsoftonline.com/$-your-client-ID/oauth2/v2.0/authorize

JWK Set URI:
https://login.microsoftonline.com/$-your-client-ID/discovery/v2.0/keys

Token URI:
https://login.microsoftonline.com/$-your-client-ID/oauth2/v2.0/token

User Info URI:
https://graph.microsoft.com/oidc/userinfo

Advanced configuration

The username attribute from the OIDC provider contains the unique username of the authenticated user.

The username attribute in Relution contains the unique username of the authenticated user.

Authorization Grant Type` The Authorization Grant Type is an OAuth mechanism that specifies how an application obtains access permissions from a user.

Scope Scopes define what identity information or resources the application can request from the OIDC provider

Settings in Azure

Creating a new app registry

Logging in in Azure Portal, continuing on Azure Active Directory.
Creating new App registry > Create new registry for OIDC.
Naming application, selecting account type Only accounts in this organization directory and regesting it.

Adding secret client key (Client Secret) under Certificates & Secrets

The required client secret is created under Add a certificate or secret.
Via New secret client key the Description and validity period Valid until can be set.
The client key can be copied directly.

💡

The client key is displayed only once!

💡

When the validity period expires, there will be no connection and Relution will not be able to communicate with Azure. In this case, a new `secret client key` must be created for the application in Azure and re-transmitted to Relution.

Configure API permissions.

Under API Permissions > Configured Permissions, Add Permission should be clicked.
The Microsoft Graph should be selected under Microsoft APIs in the Request API Permissions dialogue box.

In the next step, the tile `Application permissions can be selected.
User.Read.All for can be selected for User

💡

For the newly added API permissions, an exclamation mark is initially displayed as the status. Administrators must agree to this once in order for Microsoft Graph to ultimately receive the permissions. Afterwards, the status is displayed with a green check mark for `Granted` and the permissions are granted.

Add redirection URI

💡

The redirection URI will be displayed in the Relution portal once the connection is configured and saved.
