Available in [Grafana Enterprise]({{< relref "../../../../introduction/grafana-enterprise" >}}) version 10.0 and later, and [Grafana Cloud Pro and Advanced](/docs/grafana-cloud/).
You can configure SAML authentication in Grafana through the user interface (UI) or the Grafana configuration file. For instructions on how to set up SAML using the Grafana configuration file, refer to [Configure SAML authentication using the configuration file]({{< relref "../saml" >}}).
Any configuration changes made through the Grafana user interface (UI) will take precedence over settings specified in the Grafana configuration file or through environment variables. This means that if you modify any configuration settings in the UI, they will override any corresponding settings set via environment variables or defined in the configuration file. For more information on how Grafana determines the order of precedence for its settings, please refer to the [Settings update at runtime]({{< relref "../../../configure-grafana/settings-updates-at-runtime" >}}).
Disabling the UI does not affect any configuration settings that were previously set up through the UI. Those settings will continue to function as intended even with the UI disabled.
- Grafana instance running Grafana version 10.0 or later with [Grafana Enterprise]({{< relref "../../../../introduction/grafana-enterprise" >}}) or [Grafana Cloud Pro or Advanced](/docs/grafana-cloud/) license.
It is possible to set up Grafana with SAML authentication using Azure AD. However, if an Azure AD user belongs to more than 150 groups, a Graph API endpoint is shared instead.
Grafana versions 11.1 and below do not support fetching the groups from the Graph API endpoint. As a result, users with more than 150 groups will not be able to retrieve their groups. Instead, it is recommended that you use OIDC/OAuth workflows.
As of Grafana 11.2, the SAML integration offers a mechanism to retrieve user groups from the Graph API.
| **Allow signup** | If enabled, you can create new users through the SAML login. If disabled, then only existing Grafana users can log in with SAML. |
| **Auto login** | If enabled, Grafana will attempt to automatically log in with SAML skipping the login screen. |
| **Single logout** | The SAML single logout feature enables users to log out from all applications associated with the current IdP session established using SAML SSO. For more information, refer to [SAML single logout documentation]]({{<relref"../saml#single-logout">}}). |
| **Identity provider initiated login** | Enables users to log in to Grafana directly from the SAML IdP. For more information, refer to [IdP initiated login documentation]({{< relref "../saml#idp-initiated-single-sign-on-sso" >}}). |
For more information, refer to an [example on how to generate SAML credentials]({{< relref "../saml#generate-private-key-for-saml-authentication" >}}).
1. In the **Sign requests** field, specify whether you want the outgoing requests to be signed, and, if so, which signature algorithm should be used.
The SAML standard recommends using a digital signature for some types of messages, like authentication or logout requests to avoid [man-in-the-middle attacks](https://en.wikipedia.org/wiki/Man-in-the-middle_attack).
1. If you wish to [map user information from SAML assertions]({{< relref "../saml#assertion-mapping" >}}), complete the **Assertion attributes mappings** section.
You also need to configure the **Groups attribute** field if you want to use team sync. Team sync automatically maps users to Grafana teams based on their SAML group membership.
Learn more about [team sync]({{< relref "../../configure-team-sync" >}}) and [configuring team sync for SAML]({{< relref "../saml#configure-team-sync" >}}).
1. If you want to automatically assign users' roles based on their SAML roles, complete the **Role mapping** section.
First, you need to configure the **Role attribute** field to specify which SAML attribute should be used to retrieve SAML role information.
Then enter the SAML roles that you want to map to Grafana roles in **Role mapping** section. If you want to map multiple SAML roles to a Grafana role, separate them by a comma and a space. For example, `Editor: editor, developer`.
Role mapping will automatically update user's [basic role]({{< relref "../../../../administration/roles-and-permissions/access-control#basic-roles" >}}) based on their SAML roles every time the user logs in to Grafana.
Learn more about [SAML role synchronization]({{< relref "../saml#configure-role-sync" >}}).
1. If you're setting up Grafana with Azure AD using the SAML protocol and want to fetch user groups from the Graph API, complete the **Azure AD Service Account Configuration** subsection.
1. Set up a service account in Azure AD and provide the necessary details in the **Azure AD Service Account Configuration** section.
1. Provide the **Client ID** of your Azure AD application.
1. Provide the **Client Secret** of your Azure AD application, the **Client Secret** will be used to request an access token from Azure AD.
1. Provide the Azure AD request **Access Token URL**.
1. If you don't have users with more than 150 groups, you can still force the use of the Graph API by enabling the **Force use Graph API** toggle.
1. If you have multiple organizations and want to automatically add users to organizations, complete the **Org mapping section**.
First, you need to configure the **Org attribute** field to specify which SAML attribute should be used to retrieve SAML organization information.
Now fill in the **Org mapping** field with mappings from SAML organization to Grafana organization. For example, `Org mapping: Engineering:2, Sales:2` will map users who belong to `Engineering` or `Sales` organizations in SAML to Grafana organization with ID 2.
If you want users to have different roles in different organizations, you can additionally specify a role. For example, `Org mapping: Engineering:2:Editor` will map users who belong to `Engineering` organizations in SAML to Grafana organization with ID 2 and assign them Editor role.
Organization mapping will automatically update user's organization memberships (and roles, if they have been configured) based on their SAML organization every time the user logs in to Grafana.
- If there are issues with your configuration, an error message will appear. Refer back to the previous steps to correct the issues and click on `Save and apply` on the top right corner once you are done.
