When I try to list a folder on behalf of another user I get the error message.
Bearer realm="Service", error="insufficient_scope", error_description="The request requires higher privileges than provided by the access token."My scopes: root_readwrite,manage_managed_users,gcm
I test it with an account not connected to the account which have created the application, with a co-admin role. Of course I have as-user option activated on the application. Do I need to add another scope?
Alternatively, how to list root folders of all users belonging to an organization?
