Hi,

That isn't a password. The token handles the user authentication side of
things, and is time-stamped. There isn't enough info in the .ica file to let
you do any more than launch a DOS attack against the CSG server.

Regards,

Rick

I was hoping that someone on this list would have an answer to this question
that I could forward to the Canadian list.
 
Thanks!

I noticed that the ICA file sent by the NFuse server (in a CSG deployment)
contains the ticket, CSG gateway DNS name and encrypted NT domain and
password.  If an intruder taps in to the SSL stream and able to crack the NT
domain and password, wouldn't they be able to use it and log in as the user
regardless of the ticket? All they really need is the user name, password
and domain to log in. How true is this and how can it be deemed safe and
secure?
 
Thanks
 
Emerson
