Grafana - Configure generic OAuth2 authentication

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
• Keycloak 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 using different methods and includes examples of setting up generic OAuth2 with specific OAuth2 providers.

Before you begin

To follow this guide:

• Ensure you know how to create an OAuth2 application with your OAuth2 provider. Consult the documentation of your OAuth2 provider for more information.
• Ensure your identity provider returns OpenID UserInfo compatible information such as the sub claim.
• 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.

Configure generic OAuth authentication client using the Grafana UI

Note
Available in Public Preview in Grafana 10.4 behind the ssoSettingsApi feature toggle.

As a Grafana Admin, you can configure Generic OAuth2 client from within Grafana using the Generic OAuth UI. To do this, navigate to Administration > Authentication > Generic OAuth page and fill in the form. If you have a current configuration in the Grafana configuration file then the form will be pre-populated with those values otherwise the form will contain default values.

After you have filled in the form, click Save to save the configuration. If the save was successful, Grafana will apply the new configurations.

If you need to reset changes you made in the UI back to the default values, click Reset. After you have reset the changes, Grafana will apply the configuration from the Grafana configuration file (if there is any configuration) or the default values.

Note
If you run Grafana in high availability mode, configuration changes may not get applied to all Grafana instances immediately. You may need to wait a few minutes for the configuration to propagate to all Grafana instances.

Refer to configuration options for more information.

Configure generic OAuth authentication client using the Terraform provider

Note
Available in Public Preview in Grafana 10.4 behind the ssoSettingsApi feature toggle. Supported in the Terraform provider since v2.12.0.

terraform

resource "grafana_sso_settings" "generic_sso_settings" {
  provider_name = "generic_oauth"
  oauth2_settings {
    name              = "Auth0"
    auth_url          = "https://<domain>/authorize"
    token_url         = "https://<domain>/oauth/token"
    api_url           = "https://<domain>/userinfo"
    client_id         = "<client id>"
    client_secret     = "<client secret>"
    allow_sign_up     = true
    auto_login        = false
    scopes            = "openid profile email offline_access"
    use_pkce          = true
    use_refresh_token = true
  }
}

Refer to Terraform Registry for a complete reference on using the grafana_sso_settings resource.

Configure generic OAuth authentication client using the Grafana configuration file

Ensure that you have access to the Grafana configuration file.

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.
2. Optional: Configure a refresh token:

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

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

c. Enable the refresh token on the provider if required.
3. Configure role mapping.

4. Optional: Configure team synchronization.

5. 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.

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:

Source of login	Required configuration
login or username field of the OAuth2 ID token.	N/A
Another field of the OAuth2 ID token.	Set login_attribute_path configuration option.
login or username field of the user information from the UserInfo endpoint.	N/A
Another field of the user information from the UserInfo endpoint.	Set login_attribute_path configuration option.

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:

Source of display name	Required configuration
name or display_name field of the OAuth2 ID token.	N/A
Another field of the OAuth2 ID token.	Set name_attribute_path configuration option.
name or display_name field of the user information from the UserInfo endpoint.	N/A
Another field of the user information from the UserInfo endpoint.	Set name_attribute_path configuration option.

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:

Source of email address	Required configuration
email field of the OAuth2 ID token.	N/A
attributes map of the OAuth2 ID token.	Set email_attribute_name configuration option. By default, Grafana searches for email under email:primary key.
upn field of the OAuth2 ID token.	N/A
email field of the user information from the UserInfo endpoint.	N/A
Another field of the user information from the UserInfo endpoint.	Set email_attribute_path configuration option.
Email address marked as primary from the /emails endpoint of the OAuth2 provider (obtained by appending /emails to the URL configured with api_url)	N/A

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 v10.3.0 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 Admin, Editor, Viewer or None.

Payload:

json

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

Config:

bash

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

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

Config:

bash

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

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

Config:

ini

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

Map one role to all users

In this example, all users will be assigned Viewer role regardless of the user information received from the identity provider.

Config:

ini

role_attribute_path = "'Viewer'"
skip_org_role_sync = false

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

groups_attribute_path = info.groups

Payload:

json

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

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.

Setting	Required	Description	Default
enabled	No	Enables generic OAuth2 authentication.	false

api_url	Yes	Endpoint used to obtain user information compatible with OpenID UserInfo.
auth_style	No	Name of the OAuth2 AuthStyle to be used when ID token is requested from OAuth2 provider. It determines how client_id and client_secret are sent to Oauth2 provider. Available values are AutoDetect, InParams and InHeader.	AutoDetect
scopes	No	List of comma- or space-separated OAuth2 scopes.	user:email
empty_scopes	No	Set to true to use an empty scope during authentication.	false
allow_sign_up	No	Controls Grafana user creation through the generic OAuth2 login. Only existing Grafana users can log in with generic OAuth if set to false.	true
auto_login	No	Set to true to enable users to bypass the login screen and automatically log in. This setting is ignored if you configure multiple auth providers to use auto-login.	false
id_token_attribute_name	No	The name of the key used to extract the ID token from the returned OAuth2 token.	id_token
login_attribute_path	No	JMESPath expression to use for user login lookup from the user ID token. For more information on how user login is retrieved, refer to Configure login.
name_attribute_path	No	JMESPath expression to use for user name lookup from the user ID token. This name will be used as the user's display name. For more information on how user display name is retrieved, refer to Configure display name.
email_attribute_path	No	JMESPath expression to use for user email lookup from the user information. For more information on how user email is retrieved, refer to Configure email address.
email_attribute_name	No	Name of the key to use for user email lookup within the attributes map of OAuth2 ID token. For more information on how user email is retrieved, refer to Configure email address.	email:primary
role_attribute_path	No	JMESPath expression to use for Grafana role lookup. Grafana will first evaluate the expression using the OAuth2 ID token. If no role is found, the expression will be evaluated using the user information obtained from the UserInfo endpoint. The result of the evaluation should be a valid Grafana role (Viewer, Editor, Admin or GrafanaAdmin). For more information on user role mapping, refer to Configure role mapping.
role_attribute_strict	No	Set to true to deny user login if the Grafana role cannot be extracted using role_attribute_path. For more information on user role mapping, refer to Configure role mapping.	false
allow_assign_grafana_admin	No	Set to true to enable automatic sync of the Grafana server administrator role. If this option is set to true and the result of evaluating role_attribute_path for a user is GrafanaAdmin, Grafana grants the user the server administrator privileges and organization administrator role. If this option is set to false and the result of evaluating role_attribute_path for a user is GrafanaAdmin, Grafana grants the user only organization administrator role. For more information on user role mapping, refer to Configure role mapping.	false
skip_org_role_sync	No	Set to true to stop automatically syncing user roles. This will allow you to set organization roles for your users from within Grafana manually.	false
groups_attribute_path	No	JMESPath expression to use for user group lookup. Grafana will first evaluate the expression using the OAuth2 ID token. If no groups are found, the expression will be evaluated using the user information obtained from the UserInfo endpoint. The result of the evaluation should be a string array of groups.
allowed_groups	No	List of comma- or space-separated groups. The user should be a member of at least one group to log in. If you configure allowed_groups, you must also configure groups_attribute_path.
allowed_organizations	No	List of comma- or space-separated organizations. The user should be a member of at least one organization to log in.
allowed_domains	No	List comma- or space-separated domains. The user should belong to at least one domain to log in.
