Random question. I don't suppose the SDK would be able to allow an authenticator to be attached to a partition context in a REST Tap? I have a Tap that uses Microsoft's OAuth provider in a Multi-tenant set up. And each tenant is a partition key. And the OAuth token endpoint URL is different for each tenant, because it must include the specific Tenant ID in the OAuth token request endpoint (it's not possible to to use the 'common' Microsoft OAuth token endpoint because the App Registration is a Multi-tenant App registration)
