The second factor is authenticating with a RADIUS proxy. The proxy
forwards the entered username and password to the RADIUS user
authentication server, starts the second factor auth and waits for the
results, with a timeout of 60 seconds. The end result is the answer to
the StrongSwan RADIUS request. If the second factor is not accepted
during this 15 second window, the authentication fails, because
EAP-Radius times out.
