I don't believe that this is possible directly with 0.7.1, but you could
simulate it with a bit of scriptery.  Basically, you want to clean out
all the "secrets" that NM stores each time the connection is dropped.
NetowrkManager sends out D-Bus signals when this happens, so you could
create a simply Python service that listens for when your network
connection starts, and then when it gets dropped, it cleans out the user
ID and the keyring secrets.

0.8.1 will have some support for One-Time-Pad tokens (like RSA SecureID)
to make the OTP password entry easier, but I hadn't yet thought about
cleaning all credentials.  That's a good enhancement request.
