Description:

I'm trying to connect to my university's WiFi which uses WPA Enterprise with MSCHAPv2. On networkmanager 1.4.x, the connection does not even start to happen. I get the error: "active connection removed before it was initialized." Running journalctl -b -u NetworkManager gives:

Versions:
Tried with networkmanager-1.4.0-1 and networkmanager-1.4.1dev+9+ga3fd485-1 with the same results.

Fixes:
Downgrading to networkmanager-1.2.5dev+5+g99e34d7-1 fixes the problem.
