We recently deployed airwave + instant APs across our school district. We ended up getting clearpass for our captive portal after we ran into some limitations with just the internal Captive portal.
Setting up clearpass has been relatively easy but I've ran into a few snags that are causing me to pull my hair out. The biggest being SSL cert issues.
We loaded our cert with no issues and if I navigate to clearpass.x.net/guest/byod-login.php I show no ssl errors and all is well. However when I push that to an ssid in airwave the end user is hit with an ssl error when the captive portal loads up.
In clearpass guest I have Secure Login via Https set.
In Airwave I'm using the following settings:
*Splash=External
*Captive portal profile=ClearpassPortal
-IP: IP to clearpass (tried fqdn, but didn't work)
-URL: /guest/byod-login.php
-Use https = enabled
-Use VC IP in Redirect URL = Enabled
*Mac Auth = Enabled
*Authentication Server = Clearpass
-RFC 3576 = Checked
-Nas IP = Ip to VC
*Accounting = Use auth servers
*Accounting Mode = Auth
*Accounting Interval = 5 min
Hopefully this is a decent amount of info, I can provide more if needed. I'm sure I'm missing something simple, but at this point I think I may be too frustrated to see it.
