At least, on my part, configuring our WiFi AP concentrator, I did nothing
in order to make that happen, I configured the captive portal web page, but
not more than that, which leads my believe it's an OS feature, rather then
AP feature. (just my opinion though, no proof).
The unit in production is an Enterasys C-25.

As for how the Captive works, in our case,  it allows any client :53
traffic, and blocks any other traffic,  also, it  resolves  any DNS query
to to its own captive portal address, once a client (identified by MAC)
authenticates, it then  stops the forced resolution to its own address,
and  lets :53 and all  traffic through, to "real" Name Servers and the www.
