Here's a little-known fact about CUWN: lightweight APs (in local mode at
any rate; I'm not sure about locally-switched Flexconnect) will just
ignore any 802.11 deauths from their clients. So even if it true that
Apple iOS devices send a deauth when they go to sleep, we'll ignore it
anyway.
One gotcha with sleeping Webauth clients comes into play if you have
some kind of L2 crypto on the WLAN. When the AP goes to rotate the
group key, sleeping clients won't respond to the group key update
messages. So then we *will* get rid of those clients. (Admittedly
it is somewhat aberrant to have L2 crypto on a Webauth WLAN.)

Second,
iPads (and possibly iPhones) send an active deauthentication when they go
to sleep or hibernate. So, they will be removed.
