Domain Mapping just redirects on first domain I map

I have created my http://www.freshapps.us installing a fresh wordpress 3.4, activated multi-site. Successfully created cName sites as a test. Then I installed domain mapping and pointed http://www.willdent.me to freshapps.us. http://www.willdent.me displays properly on public page however, when I try to log into it it just gets into this redirect back to the login page. If I enter the incorrect credentials it tells me so, however when I enter correct credentials it just shows me the login page again.
