Wireless client selects AP by MAC address

[exel]

Here's the question:

I have a wireless LAN in place at my office. Cisco G AP's, mix of Intel Centrino (2200 and 2915) and Cisco PCMCIA (AIR-CB21AG-A-K9). I'm also configured to a TACACS+ server for both Authorization and Authentication and to an AD server for user Authentication. Using WDS, TKIP, MIC, FSR and the rest.

I have a single user who configured his Intel card to point to a particular AP by MAC address. While doing failover testing of the TACACS+ servers all other users quickly reauthenticated to the backup ACS - he did not. He just kept trying to reauthenticate and failed.

Can anyone give me some insight into this situation?

Thanks.

The issue may due to WDS master is not configured to authenticate clients, just to authenticate masters alone. AP needs to be registered on the WDS to start the authentication process. For this, the AP must also be configured as if it was an Infrastructure AP (on the web interface: wireless services-AP participate in SWAN infrastructure- username and password).

Also, the infrastructure APs should not have the servers specified, they override the decisions made by the WDS, only the WDS master should. If you dont specify servers on infrastructure APs, they send the requests to the WDS master, and it will tell them to authenticate or not.
