Scaleway SAML SSO: Fixing Missing Property Mapping Docs

It's crucial to have comprehensive documentation when setting up Single Sign-On (SSO) for your cloud services. This article addresses a documentation gap in Scaleway's SAML SSO integration, specifically the absence of guidance on property mapping. We'll delve into the importance of property mapping, illustrate a practical example using Google Workspace, and highlight how correct mapping ensures seamless user authentication. Let's enhance your understanding of Scaleway SAML SSO and ensure a smoother setup process.

Understanding the Importance of Property Mapping in SAML SSO

When setting up SAML SSO (Security Assertion Markup Language Single Sign-On) with Scaleway, one critical aspect often overlooked is property mapping. Property mapping is the process of aligning user attributes between your Identity Provider (IDP) and Scaleway. Think of it as a translator, ensuring that the information passed from your IDP (like Google Workspace, Okta, or Azure AD) is correctly understood by Scaleway. Without accurate property mapping, users might face authentication failures, incorrect profile information, or even access issues.

Why is Property Mapping So Important?

• Seamless User Experience: Correctly mapped attributes ensure a smooth login process. Users can access Scaleway resources without encountering errors or needing to manually enter information.
• Accurate User Identification: Property mapping ensures that user identities are accurately transferred, preventing misidentification and ensuring the right access permissions are applied.
• Security and Compliance: By correctly mapping attributes, you maintain better control over user access and ensure compliance with security policies.
• Automation of User Provisioning: Proper mapping can streamline user provisioning and de-provisioning, reducing administrative overhead and improving security.

Consider a scenario where the "email" attribute in your IDP isn't mapped to the corresponding attribute in Scaleway. Users might be able to log in, but their accounts might not be correctly associated with their Scaleway resources, leading to access problems. Similarly, if first name and last name attributes are not mapped, user profiles within Scaleway might display incomplete or incorrect information. Therefore, understanding and correctly configuring property mapping is fundamental to a successful Scaleway SAML SSO integration. In the following sections, we will look at an example of how to configure property mapping with Google Workspace, providing a practical guide to ensure your setup is accurate and efficient. We will also discuss general principles that apply to other IDPs, empowering you to navigate the nuances of different systems and achieve a seamless integration.

Step-by-Step Guide: Configuring Property Mapping with Google Workspace for Scaleway SAML SSO

To illustrate the significance of property mapping, let's walk through a detailed example of configuring it with Google Workspace for Scaleway SAML SSO. This step-by-step guide will provide you with clear instructions and best practices to ensure a smooth integration. By correctly mapping the attributes, you ensure that user identities are accurately transferred from Google Workspace to Scaleway, leading to a seamless and secure authentication process. This process involves navigating the Google Workspace admin console and aligning specific attributes with the corresponding SAML attributes expected by Scaleway. Let’s dive into each step to ensure you have a clear understanding of the configuration process.

Step 1: Accessing the Google Workspace Admin Console

Begin by logging into your Google Workspace admin console. This is your central hub for managing Google Workspace applications and settings. Once logged in, navigate to the Apps section. This can typically be found in the main menu or dashboard of the admin console. The Apps section is where you'll manage various Google Workspace applications and integrations, including SAML SSO configurations.

Step 2: Navigating to Web and Mobile Apps

Within the Apps section, locate and click on the “Web and mobile apps” option. This section lists all the web and mobile applications configured for your Google Workspace environment, including those set up for SAML SSO. It is essential to select this option to access the settings for your Scaleway application.

Step 3: Selecting the Scaleway Application

In the list of web and mobile apps, find the Scaleway application that you previously configured for SAML SSO. If you haven't set up the Scaleway application yet, you'll need to do so before proceeding with property mapping. Once you find the Scaleway application, select it to access its configuration settings.

Step 4: Editing SAML Attributes

Within the Scaleway application settings, look for an option related to SAML attributes or SAML settings. This might be labeled as “Edit SAML attributes,” “SAML configuration,” or something similar. Click on this option to access the attribute mapping settings. This section is where you'll define how user attributes from Google Workspace are mapped to the attributes expected by Scaleway.

Step 5: Mapping Google Directory Attributes to SAML Attributes

Now, you'll see a section for attribute mapping. This is where the core configuration takes place. You need to map specific Google Directory attributes to the corresponding SAML attributes that Scaleway expects. Here are the key mappings you need to configure:

• Email: Map the Google Directory attribute for email to the SAML attribute http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress. This mapping ensures that user email addresses are correctly passed to Scaleway during authentication.
• First Name: Map the Google Directory attribute for first name to the SAML attribute http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname. This mapping ensures that user first names are correctly displayed in Scaleway.
• Last Name: Map the Google Directory attribute for last name to the SAML attribute http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname. This mapping ensures that user last names are correctly displayed in Scaleway.

Step 6: Ensuring Primary Email Field Mapping

It's crucial to ensure that the primary email field in Google Workspace is mapped to the email claim in the SAML configuration. This mapping allows Scaleway to correctly identify users during the authentication process. Without this mapping, users might encounter issues logging in or accessing resources.

Step 7: Saving the Configuration

After you've configured all the necessary attribute mappings, save the configuration. This step ensures that your settings are applied and that the attribute mappings are active. Double-check your mappings before saving to avoid any errors. Once saved, the attribute mappings will be used during the SAML authentication process.

By following these steps, you'll successfully configure property mapping between Google Workspace and Scaleway, ensuring a seamless and secure SAML SSO integration. This detailed guide helps you avoid common pitfalls and ensures that user attributes are accurately transferred, enhancing the overall user experience. In the next section, we will explore general principles for property mapping that extend beyond Google Workspace, empowering you to configure SAML SSO with other IDPs as well.

General Principles for Property Mapping Across Different IDPs

While the previous section focused on Google Workspace, the principles of property mapping apply to other Identity Providers (IDPs) as well. Understanding these general principles will enable you to configure SAML SSO with various IDPs, such as Okta, Azure AD, and others. The core concept remains the same: you need to map user attributes from your IDP to the corresponding attributes expected by Scaleway. However, the specific steps and attribute names may vary depending on the IDP. In this section, we'll outline the key principles and considerations for property mapping across different IDPs.

1. Identifying Required SAML Attributes

The first step in property mapping is to identify the SAML attributes that Scaleway requires. Typically, Scaleway will need attributes such as email address, first name, and last name.
