Yes, well you have to explicitly expect the two different outcomes and 
deal with them. Net::Telnet has built-in expect-like functionality.

s.cmd is basically a shortcut for "send this, then expect a prompt". So 
you need to use s.puts, expect with a regexp which matches either a 
normal prompt or the password expiry, and if you get a password expiry 
then deal with it appropriately.
