If a user was accessing email through a wireless AP with no security (no encryption) is the groupwise password vulnerable to attack? When groupwise is authenticated across the AP/Internet, is the password sent in clear text and visible with any wireless protocol analyzer such as AirMagnet or is it encrypted with a key shared by the Novell client and Server? Any info would be appreciated. Any other attacks that derive the groupwise user password would also be appreciated so that we can identify the threat and classify it accordingly.
