Configuring Forseti to collect G Suite data

After you set up your service account above, you may need to edit the domain_super_admin_email field in your forseti_conf_server.yaml.

If you are running Forseti on GCP and made any changes to the above values, you will need to copy the conf file to the Cloud Storage bucket. For more information, see Moving configuration to Cloud Storage.


Below are the common errors for GSuite configurations and the steps to be taken to resolve the errors.

You can find what errors have happened by running forseti inventory list|get, or look at the inventory_index_errors column in the inventory_index table.

If you make any changes to the forseti_conf_server.yaml file, be sure to update the server by reloading it with forseti server configuration reload.


('invalid_grant: Invalid email or User ID', u'{"error" : "invalid_grant", "error_description" : "Invalid email or User ID"}')

Solution: Double-check the email you entered in the domain_super_admin_email field of the forseti_conf_server.yaml file. Make sure there is no typo and the user exists.


GCP API Error: unable to get groups from GCP:
<HttpError 403 when requesting https://www.googleapis.com/admin/directory/v1/groups?customer=C04h01n68&alt=json returned "Not Authorized to access this resource/api">

Solution: Make sure you specified a super admin user in the domain_super_admin_email field of the forseti_conf_server.yaml file.


('unauthorized_client: Client is unauthorized to retrieve access tokens using this method.', u'{"error" : "unauthorized_client", "error_description" : "Client is unauthorized to retrieve access tokens using this method."}')

Solution: Make sure you entered the correct API scope(s) in the GSuite admin console.


No GSuite data and no relevant gsuite error reported by forseti inventory list|get or in inventory_index_errors column in the inventory_index table.

Solution: Make sure DwD is enabled for the server service account.
