Problem with user login on my original domain

Hello,

When users have created their own site, they have to go to their site to login (examble.forenigo.dk/wp-login.php)

It thought that when a user pressed login on the original domain forenigo.dk, they should be redirected to their own page. They don't. When they do that, they only get to change their user information and stay on my url.

Are these settings set correct?

Hope you understand my problem.
(When you press login on my page, you get this url (https://forenigo.dk/wp-login.php. I would then asume, that if a user logged in, he would automaticly be redirected to his own site as an admin.)

Best regards
Nicolaj
