Thanks -

I'm pretty confident that the signon process itself is protected, but
with out SSL, all other traffic that flows between the PC and the System
i using iSeries navigator would be in clear text.

Because iSeries Navigator uses the *SIGNON server to authenticate, I
under the impression that the iSeries navigator signon process was a
secure hash exchange and not flowing userid's and password in clear
text. Can you elaborate or explain the vulnerability here?

That would make a lot of sense, and i do not exactly know how this
services works.

I based my assumption that the logon is not secure on the fact that it
is not using SSL, but can be configured to do so:

But if it using a secure Challenge/Response way for authenticating the
user, it would be secure SSL. A quick google search did not yield
results for me, so i might be wrong.
