Unless I am misinterpreting the language here, there is a disconnect between
this document and the architecture document.

Sec 2.3 of -architecture says:
At minimum, the API MUST provide: (1) the state of captivity and (2) a URI for
the Captive Portal Server.

But in section 5 user-portal-url is an optional field. Is -architecture
actually levying a requirement on the api spec, or the api server?

I am also confused by this sentence at the end of section 4.1 about failed
authentication: “It may still be possible for the user to access the network by
being redirected to a web portal.”

Who is doing the redirecting here? If authentication has failed, how is this
redirect authenticated and secure against theft of credentials?


This document is otherwise clearly written. Thanks.

As I said in the architecture review, the term for the user portal keeps
changing. Over there it’s called a “Captive Portal Server” and a “web portal
server”. Here it’s a “user-portal.”

One nit:
