single Sign -on systems for "extranet".

["Hamaker, Chuck" <cahamake@email.uncc.edu>]

   A new breed of security management vendor is simplifying
   business-to-business e- commerce with a relatively old technology:
   single-sign-on security.

   The single-sign-on user authentication process is a technology
   originally created to give LAN users one-step access to the network.
   That's in sharp contrast to today's Web environment, in which users
   must typically endure several authentication steps each time they
   travel from one domain to another.
