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.

Possibly the AP he's connected to doesn't have the alternate ACS address in it's configuration. Check that APs config first, since that's what he's permanently associated to.

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
