ODK Aggregate local

I installed the ODK Aggregate v1.0 Alpha 5 Windows Tomcat 6 +
MySQL on a laptop.
I want to us it locally on the laptop (I mean without any internet
connection). But when I launch the http://localhost I'm asked to login
trough the gmail account.
It is possible to have a local login? What to do?
Or is possible to skip all the authorization?
