From what I can tell, they're only randomizing the MAC address on probe
requests. It appears to still use the burned in MAC address for association
and all subsequent traffic.
That said, I'd love for someone with an iOS 8 device and a suitable wireless
sniffer rig to confirm this guess =)

I have the first beta of iOS 8 installed on my iPhone 5s and it does not
appear to randomize the MAC address, nor are there any visible settings to
enable/disable that "feature." Since the MAC address remains the same while
associated to a wireless network it should not pose any issues. The original
source in the article indicates that iOS 8 will only randomize the MAC while
scanning for available networks.

Just saw this:
http://www.theverge.com/2014/6/9/5792970/ios-8-strikes-an-unexpected-blow-against-location-tracking
It wasn't touted onstage, but a new iOS 8 feature is set to cause havoc for
location trackers, and score a major win for privacy. As spotted by Frederic
Jacobs <https://twitter.com/FredericJacobs/status/475601665836744704>, the
changes have to do with the MAC address used to identify devices wi! th in
networks. When iOS 8 devices look for a connection, they randomize that
address, effectively disguising any trace of the real device until it decides
to connect to a network.

Any guesses as to how this will impact wpa2 auth or location tracking with an
MSE? (We're a Cisco wireless network with three 5508s in HA config running
current 7.6 code.)
Looking forward to your thoughts...
