Lightdm asks for wireless password for eduroam on each start

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu:
Happens on Ubuntu 14.04 amd64, Ubuntu 14.10 amd64
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
uptodate 14.10 package
3) What you expected to happen
Save the password of the wireless eduroam (PEAP/MSCHAPv2 without CA certificate) network when entered on lightdm
4) What happened instead

The problem I have is connected with my university's eduroam wireless network. When I connect to it the first time I have to choose PEAP and MSCHAPv2, when I want to save the connection it tells about the missing CA certificate, so I tell it to ignore it. This works fine but when I start up the system in lightdm I get asked to reinsert the password of the eduroam connection, but even when I insert the password and click on ignore the CA certificate message I have to do this procedure on each restart of the system.

I'm not alone with this problem: http://askubuntu.com/questions/516406/ubuntu-14-04-disable-automatic-network-connection-until-after-login / https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1104476/comments/156 - So my problem is somehow related to this bugreport ( https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1104476 ), when ignoring the CA certificate message it will connect but not save the password at the login-screen.

So how do I get rid of this nagging request at each login?
