Instant & CPPM - CPGuest Portal not sending radius request to CPPM

Hello there,

 

I am facing a strange issue since I changed the certificates on my Instant VC and my CPG portal.

 

All was working before.

 

When a user is registered and enabled from SR portal, he is getting a register loop.

 

On CPPM, there isn't log in the Access Tracker.

 

I am using :

- Self Registration portal from CP Guest

- User authentication with mac caching policies on CPPM

- Instant VC running 6.5.4.12 with 205 and 305 IAPs

 

Here's my Instant configuration :

 

name ctl.portail-guest.com
dynamic-radius-proxy

mas-integration
extended-ssid



wlan access-rule Guests
 index 5

Any ideas why my VC is not sending Radius auth request when my client device is redirected after successful registering?

And I don't understand why it has stoped running after changing SSL certificates...

 

Many thanks

Re: Instant & CPPM - CPGuest Portal not sending radius request to CPPM

Hello,

 

Did you change just the certificate or the hostname too of the controller?

I would check few things below first:

1. Is the client able to resolve the hostname of the controller? Nslookup etc.

2. When you enter the credentails and click on login on the client, what is the url that it trying to post the credentials to?

3. pcap from the client machine, would show, if the client is able to post the credentials or not, and failing?

4. If the client is not able to post the credentails and failing, we need to look at the acl's.

 

you mentioned it was working before and stopped working after you updating the certificate? did the CN name changed on the certificate? if yes, we need to update the CN name on the Clearpass Guest configuration, under NAS vendor settings.

Re: Instant & CPPM - CPGuest Portal not sending radius request to CPPM

Many thanks for sharing your findings.

I finallly resolved the issue :

I changed the previous signed SSL certificate with a wildcard certificate.
I needed to change the CN name on the Guest NAS vendor settings to captiveportal-login.mydomain.com.

All is working fine now.

I am a little bit confused about certificate configuration with Instant APs... Is there any guide mentioning certificate import and wildcard certificate specific process ?

Hello Jeremy,

 

Great news, I am glad that i was helpful for you. I would recommend looking at aruba instant user guide and also this article, should also be explaining about installing cert on IAP:
