We have a guest network with a customized web page right now. When the user connects, it asks for their name and logs it to a RADIUS server. However, the user can leave this field blank and press enter to gain access. Is there some way to force a user to enter their name into this page before access can be granted? We don't want to enter a username for each user because there are too many. I found this page and this is what we want to happen (I can't figure out how to do it).
We would like a page like this, but the user MUST enter a name or email before proceeding. No password is required. Down the road, we will attempt to verify the email that they enter, however we are not worried about that now.
