I have a guest network set up that is completely isolated from production, the intent being that visitors are issued a username and can go out to the Internet while they are visiting. I'd like to fix one thing: The visitor connects to the wireless network, and a Cisco login (webauth) page appears... but before it does, the visitor has to accept invalid certificate warnings. Is there a free certificate, or perhaps something that is self-signed that can bridge the gap, or do I have to buy a certificate to remove this warning? I'm open to any workarounds, as this is a new installation and changes are easy to make now.
Thanks!
Dan
