Literally, it will affect at least 100 people from our company, when their passwords will expire.
While password, entered into 15.10 release, were walid, everything worked.
Today, I ought to change my password. And new password is simply not stored anywhere.
Neither works "ask every time" option, it just appears again and again, without result.

I did the same workaround:
- wrote plaintext password to /etc/NetworkManager/system-connections/ConnectionName
- restart NetworkManager

But it is awful workaround, don't you think so?
