Bug Description

My university campus uses the Eduroam (https://www.eduroam.org) standard for its Wi-Fi access points. I have saved my authentication details for this access point using Ubuntu 13.04's standard network manager and it connects automatically as such after a return from suspend. When booting the machine and getting to LightDM, however, I am prompted to enter my password for the Eduroam access point. This should authenticate automatically, as I have saved the password, as it did in Ubuntu 12.04 and 12.10.

I'm seeing this same thing with an Eduroam wifi, it used to work in until 12.10 but now in 13.04 it always asks me for the password when booting. I have tried everything available for similar problems and I cannot get it to work.

I stumbled upon this configuration file, which goes in /etc/NetworkManager/system-connections/eduroam:

[ipv6]
method=auto
ip6-privacy=2

[connection]
id=eduroam
uuid=2fb6ac81-bb1c-44df-ba87-f0ec95e3d0d1
type=802-11-wireless
timestamp=1349875620

[802-11-wireless]
ssid=eduroam
mode=infrastructure
security=802-11-wireless-security

[802-1x]
eap=ttls;
identity=<change this>@studserv.uni-leipzig.de
phase2-auth=pap
password=<change this>

[ipv4]
method=auto

[802-11-wireless-security]
key-mgmt=wpa-eap

Mine was almost identical, but did not have the line which starts with "password". After introducing this line (and deleting two other lines that appeared in my configuration file but not here) now after rebooting "eduroam" does not ask for a password any more.

So it seems that the bug is that after editing the connection in the NetworkManager GUI this password line is not saved in the system configuration file, if I understand correctly how nm works.
