Ok, there is some confusion here.

You are using a captive portal, so it's actually your captive portal 
web-based login that is doing CHAP - the Apple/Android devices are just 
doing HTTP forms-based login.

If Apple devices aren't working, it's a problem with the captive portal. 
Captive portals are just web pages from the client point of view.
