Generic OIDC Provider

This guide explains how to configure any OIDC-compliant authentication provider for Feldera Enterprise.

Overview

Feldera supports standard OIDC/OAuth2 authentication, allowing you to integrate with any OIDC-compliant identity provider such as Auth0, Keycloak, Azure AD, Google Identity, or other enterprise identity providers.

OIDC Application Setup

1. Create OIDC Application

In your OIDC provider's admin console:

1. Create a new application or client
2. Select Single-Page Application (SPA) as the application type
3. Fill in application details:
   • Application name: Feldera (or your preferred name)
   • Application description: Optional description for your organization

2. Configure Grant Types

Enable the following OAuth 2.0 grant types:

• Authorization Code grant type (required)
• Refresh Token (recommended for long-lived sessions)
• PKCE (Proof Key for Code Exchange) - highly recommended for security

3. Configure Redirect URLs

Add the following URLs to your OIDC application configuration:

• Sign-in redirect URI: https://<your-feldera-domain>/auth/callback/
• Sign-out redirect URI: https://<your-feldera-domain>/

note

Important: The trailing slash (/) in the callback URL must be included. Most OIDC providers require exact URL matching.

4. Configure Scopes

Ensure the following OpenID Connect scopes are allowed:

• openid (required)
• profile (recommended)
• email (required)
• offline_access (required)

Tenant Assignment (Optional)

Feldera supports authorization through multiple tenant assignment strategies. By default, each user gets their own individual tenant based on the sub claim.

Multi-Tenant Access with Custom Claims

To enable managed tenancy, configure your OIDC provider to include custom claims in the Access token:

tenants Claim

Configure your OIDC provider to include a tenants claim in the Access token:

• Claim name: tenants
• Token type: Access Token
• Value type: Array of strings or comma-separated string
• Value: List of tenant names the user can access

Example token claim:

{
  "tenants": ["engineering", "data-science", "analytics"]
}

When multiple tenants are configured, users can switch between tenants in the Web Console or specify the tenant using the Feldera-Tenant HTTP header.

Group-Based Authorization (Optional)

To restrict access based on group membership, configure your OIDC provider to include a groups claim in the Access token:

• Claim name: groups
• Token type: Access Token
• Value type: Array of strings
• Value: List of group names the user belongs to

Example token claim:

{
  "groups": ["feldera-users", "data-engineers", "admins"]
}

When authorizedGroups is configured in Feldera, users must have at least one matching group to access the platform.

Configure Feldera

After setting up your OIDC provider, configure Feldera using the Helm chart values; see examples for common authorization scenarios.
