Caveats

Caveats

This section describes the open, resolved, and closed caveats for the software components in this release.

Open Caveats

The following caveats are not resolved in CB21AG and PI21AG client adapter software release 3.0:

•CSCsd31365—When the client connects to an access point that does not broadcast its SSID, the Cisco Aironet Site Survey Utility AP Scan List may not the access point’s SSID for a short time.

•CSCsd80390—The “No machine certificates were found on your computer” message is misleading

When using the Cisco AIR-CB21AG-A-K9 802.11/a/b/g client adapters and running ADU 2.6.0.1, if you try to select ADU clients using EAP-TLS authentication, you see a message stating that no machine certificates were found on your computer, even though the application automatically finds the machine certificates. Also, if you select Use machine Information for Domain Logon under EAP-TLS configuration, you get the same error message. This message will not cause any problem and should only be seen once.

•CSCsd86612—If a user enters an incorrect password, the ADU will prompt the user to re-enter the password, but the ACS server will not record an invalid login attempt in its logs.

This behavior is by design. The ACS server does not log an EAP failure because it gives the user a chance to reauthenticate.

•CSCse05471—The CB21 client adapter cannot pass the authentication phase with a Traditional Chinese username

This only occurs on a machine with the Traditional Chinese language pack and a 2-byte username. When configuring the EAP-FAST authentication with Machine PAC, the STAUT failed to roam between access points.

•CSCse25438—The Advanced Status window of the ADU application shows the wrong SSID information

In the ADU application, if you click Current Status and Advanced, you will notice that the Network Name (SSID) field displays only the first two characters of the SSID in the Advanced Status window. This happens when the SSID is a long string of characters with white spaces in between. The window wraps the string around into multiple lines and shows only one line.

•CSCse37717—EAP-FAST roaming fails with machine PAC

Workaround: Uncheck the session resume check box in the ACS 4.0 RADIUS server.
