It seems like there is a number of Android devices that have issues validating
the server certificate for 802.1x authentication.
We did some research and it seems like it is a common issue with different
Android OS and hardware flavors. We can’t put our finger on it but it seems like
it is the native 802.1x supplicant within Android.
There are 3rd party supplicants but at this point this is not one that we can
recommend.
We do not encourage anyone to connect to the ESSID “DefCon” without validating
the server certificate.
As for the steps to correctly configure it:
The configuration above is pretty much the same for any other devices out there.
Any further updates on this matter will be posted here.
