Configure generic OAuth2 authentication

There are numerous authentication methods available in Grafana to verify user identity. The authentication configuration dictates which users can access Grafana and the methods they can use for logging in. You can also configure Grafana to automatically update users’ roles and team memberships in Grafana based on the information returned by the auth provider integration.

When deciding on an authentication method, it’s important to take into account your current identity and access management system as well as the specific authentication and authorization features you require. For a complete list of the available authentication options and the features they support, refer to Configure authentication.

Grafana provides OAuth2 integrations for the following auth providers:

• Azure AD OAuth
• GitHub OAuth
• GitLab OAuth
• Google OAuth
• Grafana Com OAuth
• Okta OAuth

If your OAuth2 provider is not listed, you can use generic OAuth2 authentication.

This topic describes how to configure generic OAuth2 authentication and includes examples of setting up generic OAuth2 with specific OAuth2 providers.

Before you begin

To follow this guide:

• Ensure that you have access to the Grafana configuration file.
• Ensure you know how to create an OAuth2 application with your OAuth2 provider. Consult the documentation of your OAuth2 provider for more information.
• If you are using refresh tokens, ensure you know how to set them up with your OAuth2 provider. Consult the documentation of your OAuth2 provider for more information.

Steps

To integrate your OAuth2 provider with Grafana using our generic OAuth2 authentication, follow these steps:

1. Create an OAuth2 application in your chosen OAuth2 provider.

2. Set the callback URL for your OAuth2 app to http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/generic_oauth.

   Ensure that the callback URL is the complete HTTP address that you use to access Grafana via your browser, but with the appended path of /login/generic_oauth.

   For the callback URL to be correct, it might be necessary to set the root_url option in the [server]section of the Grafana configuration file. For example, if you are serving Grafana behind a proxy.

3. Refer to the following table to update field values located in the [auth.generic_oauth] section of the Grafana configuration file:

   Field	Description
   client_id, client_secret	These values must match the client ID and client secret from your OAuth2 app.
   auth_url	The authorization endpoint of your OAuth2 provider.
   api_url	The user information endpoint of your OAuth2 provider. Information returned by this endpoint must be compatible with OpenID UserInfo.
   enabled	Enables generic OAuth2 authentication. Set this value to true.

   Review the list of other generic OAuth2 configuration options and complete them, as necessary.

4. Optional: Configure a refresh token:

   a. Enable accessTokenExpirationCheck feature toggle.

   b. Extend the scopes field of [auth.generic_oauth] section in Grafana configuration file with refresh token scope used by your OAuth2 provider.

   c. Set use_refresh_token to true in [auth.generic_oauth] section in Grafana configuration file.

   d. Enable the refresh token on the provider if required.

5. Configure role mapping.

6. Optional: Configure team synchronization.

7. Restart Grafana.

   You should now see a generic OAuth2 login button on the login page and be able to log in or sign up with your OAuth2 provider.

Configuration options

The following table outlines the various generic OAuth2 configuration options. You can apply these options as environment variables, similar to any other configuration within Grafana.

Configure login

Grafana can resolve a user’s login from the OAuth2 ID token or user information retrieved from the OAuth2 UserInfo endpoint. Grafana looks at these sources in the order listed until it finds a login. If no login is found, then the user’s login is set to user’s email address.

Refer to the following table for information on what to configure based on how your Oauth2 provider returns a user’s login:

Configure display name

Grafana can resolve a user’s display name from the OAuth2 ID token or user information retrieved from the OAuth2 UserInfo endpoint. Grafana looks at these sources in the order listed until it finds a display name. If no display name is found, then user’s login is displayed instead.

Refer to the following table for information on what you need to configure depending on how your Oauth2 provider returns a user’s name:

Configure email address

Grafana can resolve the user’s email address from the OAuth2 ID token, the user information retrieved from the OAuth2 UserInfo endpoint, or the OAuth2 /emails endpoint. Grafana looks at these sources in the order listed until an email address is found. If no email is found, then the email address of the user is set to an empty string.

Refer to the following table for information on what to configure based on how the Oauth2 provider returns a user’s email address:

Configure a refresh token

Note: This feature is behind the accessTokenExpirationCheck feature toggle.

When a user logs in using an OAuth2 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.

To configure generic OAuth2 to use a refresh token, set use_refresh_token configuration option to true and perform one or both of the following steps, if required:

1. Extend the scopes field of [auth.generic_oauth] section in Grafana configuration file with additional scopes.
2. Enable the refresh token on the provider.

Note: The accessTokenExpirationCheck feature toggle will be removed in Grafana v10.2.0 and the use_refresh_token configuration value will be used instead for configuring refresh token fetching and access token expiration check.

Configure role mapping

Unless skip_org_role_sync option is enabled, the user’s role will be set to the role retrieved from the auth provider upon user login.

The user’s role is retrieved using a JMESPath expression from the role_attribute_path configuration option. To map the server administrator role, use the allow_assign_grafana_admin configuration option. Refer to configuration options for more information.

If no valid 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. This setting denies user access if no role or an invalid role is returned.

To ease configuration of a proper JMESPath expression, go to JMESPath to test and evaluate expressions with custom payloads.

Role mapping examples

This section includes examples of JMESPath expressions used for role mapping.

Map user organization role

In this example, the user has been granted the role of an Editor. The role assigned is based on the value of the property role, which must be a valid Grafana role such as Viewer, Editor or Admin.

Payload:

json Copy

{
    ...
    "role": "Editor",
    ...
}

Config:

bash Copy

role_attribute_path = role

In the following more complex example, the user has been granted the Admin role. This is because they are a member of the admin group of their OAuth2 provider. If the user was a member of the editor group, they would be granted the Editor role, otherwise Viewer.

Payload:

json Copy

{
    ...
    "info": {
        ...
        "groups": [
            "engineer",
            "admin",
        ],
        ...
    },
    ...
}

Config:

bash Copy

role_attribute_path = contains(info.groups[*], 'admin') && 'Admin' || contains(info.groups[*], 'editor') && 'Editor' || 'Viewer'

Map server administrator role

In the following example, the user is granted the Grafana server administrator role.

Payload:

json Copy

{
    ...
    "info": {
        ...
        "roles": [
            "admin",
        ],
        ...
    },
    ...
}

Config:

ini Copy

role_attribute_path = contains(info.roles[*], 'admin') && 'GrafanaAdmin' || contains(info.roles[*], 'editor') && 'Editor' || 'Viewer'
allow_assign_grafana_admin = true

Configure team synchronization

Note: Available in Grafana Enterprise and Grafana Cloud.

By using Team Sync, you can link your OAuth2 groups to teams within Grafana. This will automatically assign users to the appropriate teams. Teams for each user are synchronized when the user logs in.

Generic OAuth2 groups can be referenced by group ID, such as 8bab1c86-8fba-33e5-2089-1d1c80ec267d or myteam. For information on configuring OAuth2 groups with Grafana using the groups_attribute_path configuration option, refer to configuration options.

To learn more about Team Sync, refer to Configure team sync.

Team synchronization example

Configuration:

bash Copy

groups_attribute_path = info.groups

Payload:

json Copy

{
    ...
    "info": {
        ...
        "groups": [
            "engineers",
            "analysts",
        ],
        ...
    },
    ...
}

Examples of setting up generic OAuth2

This section includes examples of setting up generic OAuth2 integration.
