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 2.5. • CSCeh59294—Failure to find domain controller during LEAP authentication The client adapter may be unable to find a domain controller when attempting to LEAP authenticate. This state can be a normal condition due to network unavailability.
Caveats • CSCsb81180—Client adapters may randomly disassociate Client adapters may randomly disassociate from their access points and then fail to reassociate. To work around this problem, reboot the client. • CSCsb90765—Client adapter fails to reassociate after WLSM is reset When the Wireless LAN Services Module (WLSM) is rebooted, the client adapter disassociates from its access point.
Caveats • CSCeh69073 and CSCeh72204—Auto-provisioned PAC does not support unicode usernames An auto-provisioned PAC is not stored in a user’s private store if he or she logs into Windows with a username containing two-byte characters. Automatic PAC provisioning succeeds, but the PAC does not appear in the Select EAP-FAST PAC window of the private store and therefore cannot be deleted.
Troubleshooting • CSCeh66882—User is prompted for EAP-FAST PAC when it should be present The following message may appear even if you have already specified a PAC to use with EAP-FAST: “The current EAP-FAST profile does not have a PAC or the configured PAC does not match the authentication server.
