Hi David,

Aaron here from Cal Poly University in San Luis Obispo...

*Do you*:

- Support 802.1x? -

Yes.


*If yes, do you*:

- use EAP-PEAP on campus? -

Yes.

- use EAP-TLS on campus? -

Yes.

- What PKI/CA do you use: -

For PEAP, we use Comodo/Incommon as the CA for the RADIUS and HTTPS certs
that we load into Aruba Clearpass, which acts as our RADIUS.  For EAP-TLS,
we use Aruba Clearpass Onboarding, which acts as its own PKI, and again, we
use Comodo/Incommon as the CA for the RADIUS and HTTPS certs in Clearpass.

- If both, why and is one preferred? -

We started out with PEAP, then rolled in EAP-TLS; the reason for this was
that because we're Education, we don't have centralized management of
devices, but rather BYOD, so getting certs to users' devices so that the
devices bark less was difficult.  With PEAP, we made a mobile config
profile available to IOS users so that those devices barked less about
seeing a new cert--you still get a "I see a new cert" popup in IOS/AppleOS
but at least there's no dreaded "Not Verified" message in red letters--then
with non-Apple devices we made do with the Root CA certs that came with the
OS, but that still meant that we had to instruct users on how to configure
the "verify server certificate" settings.

All of those certificate issues is why we started using Aruba's Onboarding
for EAP-TLS, where all we needed to worry about having valid RADIUS/HTTPS
certs on Clearpass.  The device connects to the Onboarding SSID, they login
with a browser and the device is then provisioned for our main SSID.  With
EAP-TLS, your WiFi system doesn't go down if AD has a problem because
devices are authenticated to Clearpass.  Also, there's less password
problems that come with AD, should a user's account get locked. And, if a
device is infected, you can revoke access for that one device, instead of
blocking their username and thus all their devices. But the main thing is
that your help desk theoretically has fewer visits since users can use
Onboarding anywhere.  We wanted to eventually turn off PEAP, but by having
PEAP available, there's that safety net if users cannot Onboard, and also,
we do PEAP on Eduroam as well.  Because we have ~25K devices that all want
on WiFi, there's always going to be users who, for whatever reason, are
unable to Onboard...their device is messed up, the provisioning process
crashes, etc.  That said, with PEAP there can be issues of manual device
configuration, depending upon the OS; that is less of a factor today as it
used to be, though.


- If only PEAP, are you planning EAP-TLS? -

Brief description of why you’re doing what you’re doing and anything else
that might be helpful:

One of the main issues that may influence which way you go is how sensitive
your organization is to popups on devices, in particular "certificate
cannot be verified" type messages.  Some universities don't care, just
click "OK" or "Proceed" the one time and you'll never see it again, in
which case PEAP might be okay for you.  In other universities, they won't
allow that, the whole connection experience must be as free of those popups
as possible, and that's where Aruba Onboarding helps.  As far as the manual
configuration on devices that you need to do for a PEAP connection, that
has subsided as OSes got better at WiFi; in the early days of WiFi that was
a bigger issue and is what made EAP-TLS/Onboarding so attractive.


P.S. Go Cougars...sorry man, I lived in Pullman as a kid.
