Configure SAML with Microsoft Entra ID

Grafana supports user authentication through Microsoft Entra ID. This topic shows you how to configure SAML authentication in Grafana with Entra ID.

Before you begin

Ensure you have permission to administer SAML authentication. For more information about roles and permissions in Grafana, refer to Roles and permissions.

If you have users that belong to more than 150 groups, configure a registered application to provide an Entra ID Graph API to retrieve the groups. Refer to Setup Entra ID Graph API applications.

Generate self-signed certificates

Entra ID requires a certificate to verify the SAML requests’ signature. You can generate a private key and a self-signed certificate using the following command (the private key used to sign the requests and the certificate contains the public key for verification):

sh Copy

$ openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

This will generate a key.pem and cert.pem file that you can use for the private_key_path and certificate_path configuration options.

Add Microsoft Entra SAML Toolkit from the gallery

Taken from https://learn.microsoft.com/en-us/entra/identity/saas-apps/saml-toolkit-tutorial#add-microsoft-entra-saml-toolkit-from-the-gallery

1. Go to the Azure portal and sign in with your Entra ID account.
2. Search for Enterprise Applications.
3. In the Enterprise applications pane, select New application.
4. In the search box, enter SAML Toolkit, and then select the Microsoft Entra SAML Toolkit from the results panel.
5. Add a descriptive name and select Create.

Configure the SAML Toolkit application endpoints

In order to validate Entra ID users with Grafana, you need to configure the SAML Toolkit application endpoints by creating a new SAML integration in the Entra ID organization.

For the following configuration, we will use https://localhost as the Grafana URL. Replace it with your Grafana URL.

1. In the SAML Toolkit application, select Set up single sign-on.
2. In the Single sign-on pane, select SAML.
3. In the Set up Single Sign-On with SAML pane, select the pencil icon for Basic SAML Configuration to edit the settings.
4. In the Basic SAML Configuration pane, click on the Edit button and update the following fields:
   • In the Identifier (Entity ID) field, enter https://localhost/saml/metadata.
   • In the Reply URL (Assertion Consumer Service URL) field, enter https://localhost/saml/acs.
   • In the Sign on URL field, enter https://localhost.
   • In the Relay State field, enter https://localhost.
   • In the Logout URL field, enter https://localhost/saml/slo.
5. Select Save.
6. At the SAML Certificate section, copy the App Federation Metadata Url.
   • Use this URL in the idp_metadata_url field in the custom.ini file.

Generate a client secret

1. In the Overview pane, select Certificates & secrets.
2. Select New client secret.
3. In the Add a client secret pane, enter a description for the secret.
4. Set the expiration date for the secret.
5. Select Add.
6. Copy the value of the secret. This value is used in the client_secret field in the SAML configuration.

Configure a Graph API application in Entra ID

While an Entra ID tenant can be configured in Grafana via SAML, some additional information is only accessible via the Graph API. To retrieve this information, create a new application in Entra ID and grant it the necessary permissions.

Entra ID SAML limitations

For the following configuration, the URL https://localhost will be used as the Grafana URL. Replace it with your Grafana instance URL.

Create a new App registration

This app registration will be used as a Service Account to retrieve more information about the user from the Entra ID.

1. Go to the Azure portal and sign in with your Entra ID account.
2. In the left-hand navigation pane, select the Microsoft Entra ID service, and then select App registrations.
3. Click the New registration button.
4. In the Register an application pane, enter a name for the application.
5. In the Supported account types section, select the account types that can use the application.
6. In the Redirect URI section, select Web and enter https://localhost/login/azuread.
7. Click the Register button.

Set up permissions for the application

1. In the overview pane, look for API permissions section and select Add a permission.
2. In the Request API permissions pane, select Microsoft Graph, and click Application permissions.
3. In the Select permissions pane, under the GroupMember section, select GroupMember.Read.All.
4. In the Select permissions pane, under the User section, select User.Read.All.
5. Click the Add permissions button at the bottom of the page.
6. In the Request API permissions pane, select Microsoft Graph, and click Delegated permissions.
