Connecting to public Wifi that requires user/pass in a popup window

I have a Yun that I'm trying to connect to a public Wifi. The type that once you connect you will get a popup asking for username/password.

Any guidance on how to handle this type of Wifi connection?

Depends on the router. Does it connect, then when you try to access a website, you get a user/password page? I used MikroTik routers and hotspot firmware to control internet access.

When I try to connect from my Laptop I first connect to the Wifi in question and as soon as I connect I get a popup window containing a form requesting User/Pass and a Submit button. At the bottom of the popup it shows a URL 'Success'

I haven't used apple hotspot firmware. Is it a SSL page (https)? If not, it may require other security measures. MikroTik uses CHAP. The router sends a CHAP challenge to the web browser. The web browser encrypts the password with the CHAP challenge, then returns the encrypted password and the CHAP challenge to the router. You may be able to determine this by viewing the login popup web page source.
