We worked with RIM for several hours yesterday and had a really good customer support rep. RIM has started to ask us good questions, unfortunately, no breakthrough type stuff yet.
Our plan for today is to work with an escalation manager contact at RIM and see if we can get some development or engineering resources (normal customer support reps to not have access to these resources) to at least look at our wireless packet capture. We know that the PEAP process is breaking when the BlackBerry sends back a TLS decrypt error after the certificate is sent from the IAS (RADIUS) Server.
Looks like others in an 802.1X PEAP MS-CHAP v2 WiFi environment are starting to post of problems in other forums too.
I knew we could not be the only ones having this issue...
