# Which Problems Are Solved

The current user V2 API returns a `[]byte` containing a whole HTML
document including the form on `StartIdentifyProviderIntent` for intents
based on form post (e.g. SAML POST bindings). This is not usable for
most clients as they cannot handle that and render a whole page inside
their app.
For redirect based intents, the url to which the client needs to
redirect is returned.

# How the Problems Are Solved

- Changed the returned type to a new `FormData` message containing the
url and a `fields` map.
- internal changes:
- Session.GetAuth now returns an `Auth` interfacce and error instead of
(content string, redirect bool)
- Auth interface has two implementations: `RedirectAuth` and `FormAuth`
- All use of the GetAuth function now type switch on the returned auth
object
- A template has been added to the login UI to execute the form post
automatically (as is).

# Additional Changes

- Some intent integration test did not check the redirect url and were
wrongly configured.

# Additional Context

- relates to zitadel/typescript#410
