In the power settings I also tested the option to suspend when the lid is closed. I tried this once and all seemed to work properly. In this test I didn't even have to give a password because I unchecked "Require my password when waking from suspend". This box apparanly only effects the suspend situation.
So there is an option to wake up without password from a suspend, but not after a simple close+open of the lid.
