NAC Appliance for Wifi Guest Access

[Ghost Rider]

So the name says it all..

NAC 3310 Appliance, bundled up in a failover config. 4402 WLC w/ 1242
LwAP's... WCS running control over the whole setup. Cisco Secure
Services Client on laptop..

Have done the Lobby attendant feature several times, but the first go
w/ the NAC. Client has already pre-purchased all the gear and has
just asked us to set it up.

This is just for basic authentication, no Sanity checks on A/V etc...
just new gear that is being tested for future larger scale
deployments.

Anyone have any experience/suggestions? clients needed on laptop
side? etc..

Thanks all!
