Comment 19 for bug 1173152

This is a really embarassing bug especially for us enterprise users.

Sébatien's workaround works but you're then required to enter your password each time you connect to the network.

Adding this line to etc/NetworkManager/system-connections/<network id> fixed that for me:
password=<password>

So the workaround is to remove this line:
system-ca-certs=true
and add this line in its place:
password=<password>

Though storing your password in plain text like that is not great :(
