Funk Odyssey
■The Funk Odyssey client is required
when you require WPA support on Windows 2000,
or when you need to authenticate to an LDAP
backend database that does not support
MS-CHAP-V2 over LDAP. If you choose to use this
client, please note the following:
■ Download the latest version from Funk’s website
at: www.funk.com
■ Be sure to turn off Wireless Zero Config in Win-
dows 2000 by disabling the service.
■ If your wireless NIC’s driver includes the AEGIS pro-
tocol manager for WPA support, 3Com recom-
mends against installing it. Some drivers install this
automatically if you run the setup.exe utility to
install the driver. 3Com recommends that you
update the driver manually using the driver proper-
ties in the Network control panel instead of install-
ing the client manager.
Macintosh OS/X
■OS/X Version 10.3, also known
as Panther, includes an 802.1X client that supports
Dynamic WEP and WPA/TKIP. If you choose to use
this client, please note the following:
■ The Panther client will only connect successfully to
an SSID which is only dynamic WEP, or only
WPA/TKIP. Any other configuration involving WEP
with WPA enabled or AES is not supported by the
current Panther client. If you need to run both
WPA/TKIP and Dynamic WEP at the same time you
must configured separate service profiles for each
encryption type in order to maintain compatibility
with Macintosh clients.
■ The Panther client requires you to specify the inner
and outer PEAP-MS-CHAP-V2 usernames in sepa-
rate areas. Depending on your AAA backend, both
usernames might require a domain prefix in the
form of DOMAIN\username.
Computer Authentication
Windows clients support 802.1X authentication of
the computer itself. This is called computer authenti-
cation (also known as machine authentication). Com-
puter authentication is useful when you want your
computer to be active on the domain even when no
users are logged in to the computer.
Some features of Windows XP Professional and Win-
dows 2000 Professional work correctly only with an
active network connection to the domain controller
enabled before a user is logged on to the PC. Using
computer authentication ensures that this network
connection is established during the boot sequence,
providing a wire-like infrastructure that allows you to
use the following features on a wireless network.
The following table lists Microsoft networking fea-
tures that require computer authentication.
