Description of problem:
There is a wired network, that uses 802.1x and the other side (switch?) can have enabled or disabled ports, so one has to tell admin/set it in IS where the computer is going to be connected (enabled port and correct 802.1x → working connection, enabled port and wrong 802.1x → limited connection, disabled port → link, but no connection). I plugged computer to such a disabled port.

Version-Release number of selected component:
NetworkManager-gnome-0.9.6.4-3.fc17
