## What happened?
I have a use case in which I have a backend application that hits another backend application whose url is fronted by pomerium. I am using Auth0 as IdP here, how do we configure the auth both in auth0 and pomerium for this use case?
I am assuming we should use machine-to-machine communication application in auth0 as the app identity (clientid, client secret). But as far as I know ,pomerium will automatically redirect us to the login page of the IdP in which it cannot be done on backend apps.

Yes i have read it, and there is also another page about [Service Account](https://www.pomerium.com/docs/concepts/service-accounts) but i’m not sure is it available on Core (open-sourced) version / is it exclusively available for Enterprise Version?
Because it is stated that
> A service account identity can either be based on a user entry in your IdP Directory, or exist as a custom identity managed in a Pomerium Console [Namespace](https://www.pomerium.com/docs/capabilities/namespacing).
I assume that the latter part is the enterprise capabilities.
I want to achieve the former using Auth0 as IdP (not sure what the Directory part means) rather than using custom identity managed in pomerium console.
I think there is no guide for this?
