The Azure AD authentication allows you to use an Azure Active Directory tenant as an identity provider for Grafana. You can use Azure AD application roles to assign users and groups to Grafana roles from the Azure Portal.
1. Add the following redirect URLs `https://<grafana domain>/login/azuread` and `https://<grafana domain>` then click **Register**. The app's **Overview** page opens.
1. Note the **Application ID**. This is the OAuth client ID.
1. Define the required application roles for Grafana [using the Azure Portal](#configure-application-roles-for-grafana-in-the-azure-portal) or [using the manifest file](#configure-application-roles-for-grafana-in-the-manifest-file).
1. Go to **Azure Active Directory** and then to **Enterprise Applications**.
1. Search for your application and click it.
1. Click **Users and Groups**.
1. Click **Add user/group** to add a user or group to the Grafana roles.
#### Configure application roles for Grafana in the Azure Portal
This section describes setting up basic application roles for Grafana within the Azure Portal. For more information, see [Add app roles to your application and receive them in the token](https://learn.microsoft.com/en-us/entra/identity-platform/howto-add-app-roles-in-apps).
1. Go to **App Registrations**, search for your application, and click it.
1. Click **App roles** and then **Create app role**.
1. Define a role corresponding to each Grafana role: Viewer, Editor, and Admin.
1. Choose a **Display name** for the role. For example, "Grafana Editor".
1. Set the **Allowed member types** to **Users/Groups**.
1. Ensure that the **Value** field matches the Grafana role name. For example, "Editor".
1. Choose a **Description** for the role. For example, "Grafana Editor Users".
1. Click **Apply**.
#### Configure application roles for Grafana in the manifest file
If you prefer to configure the application roles for Grafana in the manifest file, complete the following steps:
1. Go to **App Registrations**, search for your application, and click it.
1. Click **Manifest** and then click **Edit**.
1. Add a Universally Unique Identifier to each role.
{{% admonition type="note" %}}
Every role requires a [Universally Unique Identifier](https://en.wikipedia.org/wiki/Universally_unique_identifier) which you can generate on Linux with `uuidgen`, and on Windows through Microsoft PowerShell with `New-Guid`.

1. Replace each "SOME_UNIQUE_ID" with the generated ID in the manifest file:
When a user logs in using an OAuth provider, Grafana verifies that the access token has not expired. When an access token expires, Grafana uses the provided refresh token (if any exists) to obtain a new access token.
Grafana uses a refresh token to obtain a new access token without requiring the user to log in again. If a refresh token doesn't exist, Grafana logs the user out of the system after the access token has expired.
Refresh token fetching and access token expiration check is enabled by default for the AzureAD provider since Grafana v10.1.0. If you would like to disable access token expiration check then set the `use_refresh_token` configuration value to `false`.
> **Note:** The `accessTokenExpirationCheck` feature toggle has been removed in Grafana v10.3.0 and the `use_refresh_token` configuration value will be used instead for configuring refresh token fetching and access token expiration check.
To limit access to authenticated users who are members of one or more tenants, set `allowed_organizations`
to a comma- or space-separated list of tenant IDs. You can find tenant IDs on the Azure portal under **Azure Active Directory -> Overview**.
Make sure to include the tenant IDs of all the federated Users' root directory if your Azure AD contains external identities.
For example, if you want to only give access to members of the tenant `example` with an ID of `8bab1c86-8fba-33e5-2089-1d1c80ec267d`, then set the following:
Azure AD groups can be used to limit user access to Grafana. For more information about managing groups in Azure AD, refer to [Manage Microsoft Entra groups and group membership](https://learn.microsoft.com/en-us/entra/fundamentals/how-to-manage-groups).
To limit access to authenticated users who are members of one or more AzureAD groups, set `allowed_groups`
to a **comma-** or **space-separated** list of group object IDs.
1. To find object IDs for a specific group on the Azure portal, go to **Azure Active Directory > Groups**.
You can find the Object Id of a group by clicking on the group and then clicking on **Properties**. The object ID is listed under **Object ID**. If you want to only give access to members of the group `example` with an Object Id of `8bab1c86-8fba-33e5-2089-1d1c80ec267d`, then set the following:
1. You must enable adding the [group attribute](https://learn.microsoft.com/en-us/entra/identity-platform/optional-claims#configure-groups-optional-claims) to the tokens in your Azure AD App registration either [from the Azure Portal](#configure-group-membership-claims-on-the-azure-portal) or [from the manifest file](#configure-group-membership-claim-in-the-manifest-file).
#### Configure group membership claims on the Azure Portal
To ensure that the `groups` claim is included in the token, add the `groups` claim to the token configuration either through the Azure Portal UI or by editing the manifest file.
To configure group membership claims from the Azure Portal UI, complete the following steps:
1. Navigate to the **App Registrations** page and select your application.
1. Select **Token configuration**.
1. Click **Add groups claim** and select the relevant option for your use case (for example, **Security groups** and **Groups assigned to the application**).
For more information, see [Configure groups optional claims](https://learn.microsoft.com/en-us/entra/identity-platform/optional-claims#configure-groups-optional-claims).
{{% admonition type="note" %}}
If the user is a member of more than 200 groups, Azure AD does not emit the groups claim in the token and instead emits a group overage claim. To set up a group overage claim, see [Users with over 200 Group assignments](#users-with-over-200-group-assignments).
{{% /admonition %}}
#### Configure group membership claim in the manifest file
1. Go to **App Registrations**, search for your application, and click it.
1. Click **Manifest** and then click **Edit**.
1. Add the following to the root of the manifest file:
> More information in [Groups overage claim](https://learn.microsoft.com/en-us/azure/active-directory/develop/id-token-claims-reference#groups-overage-claim)
By default, Azure AD authentication will map users to organization roles based on the most privileged application role assigned to the user in AzureAD.
If no application role is found, the user is assigned the role specified by
If Azure AD authentication is not intended to sync user roles and organization membership and prevent the sync of org roles from AzureAD, set `skip_org_role_sync` to `true`. This is useful if you want to manage the organization roles for your users from within Grafana or that your organization roles are synced from another provider.
