Captive Portal / Password Requirement

[SecurityPlus]

We have a hotel that wants to use a captive portal on an interface so that the user needs to agree to terms and conditions before using the internet. We see how to set this up.

The hotel would also like to limit this access to users that have been given a password. The hotel does not want to have to create usernames/passwords for each person, but would instead like a generic password that all users would enter to use the network. They would like to change this password twice a year.

Is this possible? If so how would this be accomplished?

Some pretty serious necromancy here but, here's the basic tenant to follow.

Captive portals are typically based on http 301/302 redirects  to the portal page. 302-> https://wifi.mydomain.com/register

Now what you want to do is obtain a certificate from wifi.mydomain.com from a 3rd party vendor (DigiCert, VeriSign -aka Symantec), etc.

You'll apply this cert to the portal page your customers are redirected to, and since they have the CA in their trusted store, viola - no SSL error.
