Radius never leaves a login attempt unmarked. Whatever happens it
always issues diagnostics.

As far as I can tell here's what happens:

1) First login attempt succeeds.
2) When the second authentication arrives, radius asks the NAS whether
   the user is actually logged in, but gets no reply. (Otherwise it
   would have issued info message `check_snmp_u: got test1)
3) It then assumes the previous session had terminated abnormally and
   deletes the corresponding utmp entry.
4) When a keepalive request arrives, the entry is normally restored.
