Controllerless Networks

Hi,

I`m running a few iap225 with an external captive portal for the guest wifi. I`ve build a linux apache webserver with the external captive-portal html-page and configured the external captive portal on the aruba. When i connect to the guest-wifi, it opens the browser and displays the cp-page. But after clicking the Login-Button it reloads that cp-page and thats all.

The source-code of that page looks like:

<form method="POST" action="https://cp.host.tld/swarm.cgi">
<input type="hidden" name="cmd" value="authenticate" />
<input type="hidden" name="user" id="user" value="guest"><br>
<input type="hidden" name="password" id="password" value="guest">
<BR><input type="submit" name="Login" value="Login" class="button" />
</form>

Is there an error in the cp-page?

Is there any posibillity to debug the logon-process?

I'd recommend having a look at this blog post by Florian Baaske.

In fact, I'd recommend subscribing! Very good blog. 

I`ve already had a look at that page and build my cp-page exactly like described there :(

Is this "cp.host.tld" your DNS name on your certificate on your Instants?

thats correct. I`ve installed a wildcard-ssl-certificate for our domain on the aruba iap.

I see. That could be the problem.

Have a look at this: http://www.airheads.eu/t5/Controller-less-WLANs/Does-IAP-support-wildcard-certificate-for-captive-portal/ta-p/292431

I´m running version 6.4.4.8-4.2.4.6_58505 and regarding the release-notes that should work:

Wildcard Server Certificate Support for Captive Portal
Instant 6.4.4.8-4.2.4.4 now supports the wildcard server certificate for captive portal authentication.

That's good.This is the bit that's important:

When a wildcard SSL certificate (with CN as *.domainname.com) is installed on the IAP for captive portal authentication, IAP uses the URL as "captiveportal-login.domainname.com" to present the captive portal page. 

Therefore the following should read:

<form method="POST" action="https://captiveportal-login.host.tld/swarm.cgi">

Thank you so much, i`m working on that external captive portal thing for weeks and now its working!
