Now a question on legacy authentication

[Radia Perlman - Boston Center for Networking <Radia.Perlman@sun.com>]

It seems like EAP is just sending a string
to be displayed at the client end, and
the client (with the help of the human)
constructs a string to be sent back.

So, why is it necessary to have the legacy
authentication type sent by Bob in message 4?
It doesn't look like the client does anything
different based on the legacy authentication type.
