Thanks Travis, we have just had a couple of reports start coming in of the same.

I started getting similar reports with Yosemite.... started looking into it... I had previously configured "max-tx-fail 25" on my ssid profile. This was to try and force sticky clients from staying associated to the AP nearest the entry way. Not sure why - but appears Yosemite repeatedly hits this threshold when connecting to a network. I set this back to the default '0' [unlimited] and my yosemite macbook is connecting much more reliably. In particular I would wake up my macbook - or force a disconnect on the controller. The macbook would rejoin - auth - then drop after about 15 seconds - rejoin drop again... would repeat this a few times until stabilizing. Not sure if Yosemite is doing some form of stress analysis upon bssid - to dynamically guage when to try and roam vs using static rssi values / error counts etc... but its definitely doing something different.... This worked for my local testing with my macbook - I've pushed the change out - but don't have feedback yet. So if anyone else with Yosemite issues has max-tx-fail as a non zero value - if you change it back - let us know your results.

I believe we determined that Yosemite did not reintroduce support for EAP-TTLS (PAP). We are are dealing with numerous complaints of dropped connections too-frequent reauths (in absence of roaming or disconnects).
