Current Limitation
If a user is created with auth data, there is a single linkWith request that logs in an existing user, or if needed automatically creates a new user. Using email and password requires two separate requests, for example a log-in attempt, and if no user was found, signing up, or vice-versa.
Feature / Enhancement Description
Add new Parse Server option autoSignupOnLogin that short-circuits the login endpoint to automatically create a user if none exists yet.
