How do I get user to be directed to the homepage of the site that he applied?

I have a problem I can not solve by my own:

In the WP network, when a user registers into a subsite, he is sent to the registration page of the main site and makes the him registry. By confirming your email address and log in, it is sent to the administrative page and not the admin page of the site that he was registry.
I use the following to the registry related puglins:

Login Redirect
Multisite Privacy
Ultimate Branding

site url: http://eduwebnet.com.br
