How to configure SAML SSO with Azure
In this guide, we will use Azure as the SSO provider and with the Security Assertion Markup Language (SAML) protocol as our preferred identity protocol.
We currently support SP-initiated and IdP-initiated authentication. User provisioning is not yet supported at this time.
Step 1: Create a new application in your Identity Provider
Open a new tab/window in your browser and sign in to the Azure portal of your organization.
Navigate to “Enterprise applications” and click the “New application” button.
You’ll be redirected to this page, click on “Create your own application”, fill the name of your application, and then “Create” the application.
Then select “Single Sign-On”, and select SAML
Step 2: Configure your application on Azure
Open a new tab/window in your browser and navigate to the SSO section of your organization’s settings. Select the SAML protocol.
Copy the “SP Entity Id” from the organization’s settings on Hugging Face, and paste it in the “Identifier (Entity Id)” field on Azure (1).
Copy the “Assertion Consumer Service URL” from the organization’s settings on Hugging Face, and paste it in the “Reply URL” field on Azure (2).
The URL looks like this: https://huggingface.co/organizations/[organizationIdentifier]/saml/consume
.
Then under “SAML Certificates”, verify that “Signin Option” is set to “Sign SAML response and assertion”.
Save your new application.
Step 3: Finalize configuration on Hugging Face
In your Azure application, under “Set up”, find the following field:
- Login Url
And under “SAML Certificates”:
- Download the “Certificate (base64)”
You will need them to finalize the SSO setup on Hugging Face.
In the SSO section of your organization’s settings, copy-paste these values from Azure:
- Login Url -> Sign-on URL
- Certificate -> Public certificate
The public certificate must have the following format:
-----BEGIN CERTIFICATE-----
{certificate}
-----END CERTIFICATE-----
You can now click on “Update and Test SAML configuration” to save the settings.
You should be redirected to your SSO provider (IdP) login prompt. Once logged in, you’ll be redirected to your organization’s settings page.
A green check mark near the SAML selector will attest that the test was successful.
Step 4: Enable SSO in your organization
Now that Single Sign-On is configured and tested, you can enable it for members of your organization by clicking on the “Enable” button.
Once enabled, members of your organization must complete the SSO authentication flow described in How does it work?.
