Tom,

Our dorms are setup exactly like that, most machines now using their native supplicant will cache the credentials which will at least give the illusion of a single sign-on using the captive portal. The biggest problem we have helpdesk-wise is that we use different credentials for 802.1x and the Resnet captive portal. We are terminating the eap session on the controller and have had great success with it. You may need to play around with ssid/vlan/acl depending on what you mean by the students not being part of your domain, let me know if you'd like to discuss further!

Hello All,

We are looking to start doing 802.1x authentication on our student wireless. We are an Aruba customer and we use Cisco NAC.

Today we have an open SSID. The students connect to the SSID, open a web browser and are redirected to the Cisco NAC log on page. We would like to continue with the single sign on with NAC if possible. I think that would mean the students would have to cache their credentials in the supplicant to get authenticated to the new 802.1x SSID. Student computers are not part of our domain.

Has anyone had any experience setting up 802.1x with NAC?

Thanks,
Tom
