[keycloak-user] Authenticate user without using login page

Fri Jul 25 08:56:00 EDT 2014

Yes, but I'm wondering why the following won't work:

1. Ask for users email (in your app, not KC)
2. Once you get to the flow where a user has to login:
   a) If user doesn't exist in KC (you can use admin endpoints to check this) redirect to registration page on KC with email already entered
   b) If user does exist in KC redirect to login page again with email already entered
3. Redirect back to app
