Configure Azure AD OAuth2 authentication

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. This topic has the following sections:

Azure AD OAuth2 authentication
- Create the Azure AD application
- Enable Azure AD OAuth in Grafana

Create the Azure AD application

To enable the Azure AD OAuth2, register your application with Azure AD.

Log in to Azure Portal, then click Azure Active Directory in the side menu.
If you have access to more than one tenant, select your account in the upper right. Set your session to the Azure AD tenant you wish to use.
Under Manage in the side menu, click App Registrations > New Registration. Enter a descriptive name.
Under Redirect URI, select the app type Web.
Add the following redirect URLs https://<grafana domain>/login/azuread and https://<grafana domain> then click Register. The app’s Overview page opens.
Note the Application ID. This is the OAuth client ID.
Click Endpoints from the top menu.
- Note the OAuth 2.0 authorization endpoint (v2) URL. This is the authorization URL.
- Note the OAuth 2.0 token endpoint (v2). This is the token URL.
Click Certificates & secrets, then add a new entry under Client secrets with the following configuration.
- Description: Grafana OAuth
- Expires: Never
Click Add then copy the key value. This is the OAuth client secret.
Click Manifest, then define the required Application Role values for Grafana: Viewer, Editor, or Admin. If not defined, all users will have the Viewer role. Every role requires a unique ID which you can generate on Linux with uuidgen, and on Windows through Microsoft PowerShell with New-Guid.

Include the unique ID in the configuration file:

	"appRoles": [
			{
				"allowedMemberTypes": [
					"User"
				],
				"description": "Grafana org admin Users",
				"displayName": "Grafana Org Admin",
				"id": "SOME_UNIQUE_ID",
				"isEnabled": true,
				"lang": null,
				"origin": "Application",
				"value": "Admin"
			},
			{
				"allowedMemberTypes": [
					"User"
				],
				"description": "Grafana read only Users",
				"displayName": "Grafana Viewer",
				"id": "SOME_UNIQUE_ID",
				"isEnabled": true,
				"lang": null,
				"origin": "Application",
				"value": "Viewer"
			},
			{
				"allowedMemberTypes": [
					"User"
				],
				"description": "Grafana Editor Users",
				"displayName": "Grafana Editor",
				"id": "SOME_UNIQUE_ID",
				"isEnabled": true,
				"lang": null,
				"origin": "Application",
				"value": "Editor"
			}
		],

Go to Azure Active Directory and then to Enterprise Applications. Search for your application and click on it.
Click on Users and Groups and add Users/Groups to the Grafana roles by using Add User.

Map roles

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 the auto_assign_org_role option. You can disable this default role assignment by setting role_attribute_strict = true. It denies user access if no role or an invalid role is returned.

On every login the user organization role will be reset to match AzureAD’s application role and their organization membership will be reset to the default organization.

If Azure AD authentication is not intended to sync user roles and organization membership, oauth_skip_org_role_update_sync should be enabled. See configure-grafana for more details.

Assign server administrator privileges

Available in Grafana v9.2 and later versions.

If the application role received by Grafana is GrafanaAdmin, Grafana grants the user server administrator privileges.
This is useful if you want to grant server administrator privileges to a subset of users.
Grafana also assigns the user the Admin role of the default organization.

The setting allow_assign_grafana_admin under [auth.azuread] must be set to true for this to work.
If the setting is set to false, the user is assigned the role of Admin of the default organization, but not server administrator privileges.

{
  "allowedMemberTypes": ["User"],
  "description": "Grafana server admin Users",
  "displayName": "Grafana Server Admin",
  "id": "SOME_UNIQUE_ID",
  "isEnabled": true,
  "lang": null,
  "origin": "Application",
  "value": "GrafanaAdmin"
}

Enable Azure AD OAuth in Grafana

Add the following to the Grafana configuration file:

[auth.azuread]
name = Azure AD
enabled = true
allow_sign_up = true
client_id = APPLICATION_ID
client_secret = CLIENT_SECRET
scopes = openid email profile
auth_url = https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/authorize
token_url = https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token
allowed_domains =
allowed_groups =
role_attribute_strict = false
allow_assign_grafana_admin = false

You can also use these environment variables to configure client_id and client_secret:

GF_AUTH_AZUREAD_CLIENT_ID
GF_AUTH_AZUREAD_CLIENT_SECRET

Note: Verify that the Grafana root_url is set in your Azure Application Redirect URLs.

Configure allowed groups

To limit access to authenticated users who are members of one or more groups, set allowed_groups to a comma- or space-separated list of group object IDs. You can find object IDs for a specific group on the Azure portal:

Go to Azure Active Directory -> Groups. If you want to only give access to members of the group example with an ID of 8bab1c86-8fba-33e5-2089-1d1c80ec267d, then set the following:
```
allowed_groups = 8bab1c86-8fba-33e5-2089-1d1c80ec267d
```
Verify that group attributes is enabled in your Azure AD Application Registration manifest file by navigating to Azure Portal > Azure Active Directory > Application Registrations > Select Application -> Manifest, and set the following:
```
"groupMembershipClaims": "ApplicationGroup, SecurityGroup"
```

Configure allowed domains

The allowed_domains option limits access to users who belong to specific domains. Separate domains with space or comma. For example,

allowed_domains = mycompany.com mycompany.org

Team Sync (Enterprise only)

With Team Sync you can map your Azure AD groups to teams in Grafana so that your users will automatically be added to the correct teams.

You can reference Azure AD groups by group object ID, like 8bab1c86-8fba-33e5-2089-1d1c80ec267d.

To learn more, refer to the Team Sync documentation.

Common troubleshooting

Here are some common issues and particulars you can run into when configuring Azure AD authentication in Grafana.

Users with over 200 Group assignments

Supported in Grafana v8.5 and later versions.

To ensure that the token size doesn’t exceed HTTP header size limits, Azure AD limits the number of object IDs that it includes in the groups claim. If a user is member of more groups than the overage limit (200), then Azure AD does not emit the groups claim in the token and emits a group overage claim instead.

More information in Groups overage claim

If Grafana receives a token with a group overage claim instead of a groups claim, Grafana attempts to retrieve the user’s group membership by calling the included endpoint.

Note: The token must include the GroupMember.Read.All permission for group overage claim calls to succeed. Admin consent may be required for this permission.
