HTTPS Certifiacte failure on CGI Redirection with ProCurve Wireless EDGE Services xl Module

[Björn Andreas Höfer]

Hi,

I would like to build a wireless network for our museum-visitors.
The network is unsecured (no WEP/WPA/WPA2) but the users should accept some policies and rules with a button.

What I've done so far:
- Created a certificate request
- Installed the signed certificate
- Configured the HTTPS-Server on the Wireless Edge Module to use the certificate
- Created a new WLAN on the Wireless Edge Module
- Enabled the Web-Auth Feature (Type: External - which points to a web-server where the policy and the login screen resides)
- Created a VLAN for the guests

Now I have the following problem:
When a user connects (with an iPhone, Android, Windows 7 Laptop....) (s)he gets an certificate error

It looks like the CGI-Script in the Wireless Controller (which pops up/the users get redirected to, when they're unauthentificated) points to the IP-Adress of the Wireless Edge Module - not the hostname (which is certified).

Is there any way I can change this behavior, because I see no other option (like pointing the request over http) for handling this problem.

Maybe someone had a simmilar problem/solution which (s)he can share...

Thanks in advance
