Login and Logout Redirect behavior on multisite after update to wordpress 3.8

Hello,

I recently updated my dev multisite installation to 3.8 Parker. Unfortunately I noticed a different behavior on login and logout.

I installed logout redirect and it works only if users are on the front-end of their sites (main site included for admin).

When a non-admin user makes login, they're not anymore redirected to their site's dashboard but to the main site home page.

Can you provide some help?

Many thanks,
