Certificate based authentication with Cisco WLC and Juniper IC


I have a cisco WLC 4400 and Juniper IC which works as the external Radius server.

I want the wireless clients to be authenticated using certificates. I know the Juniper IC can understand certificates.

My question is can cisco WLC understand that the information being presented to it by the client is not username/pwd but a user certificate.


i have also looked at this article :

What i don't understand here is the need of WLC authenticating the user with his credentials by LDAP when it has authenticated the user cert.


All your help is appreciated.

Hi,Since you use an external


Since you use an external radius server you don't have to worry for this.

The only config that you need to do on WLC is to define the radius server under Security-AAA-Radius-Authentication and on your WLAN-Security-AAA.

The doc you refer is only for Local Radius on WLC.


Hope this helps

ok.So we can define a SSID in


So we can define a SSID in the WLC with WPA-2 enterprise as security.

Also what certificates need to be uploaded to WLC?

Can you point me to a document with my kind of use case scenario.

Your help would be appreciated.

No certs are needed for the

No certs are needed for the WLC. You have only to create a wpa2 ssid and define the radius server. The rest config will be on your radius server. Just search how eap-tls is deployed on juniper aaa.

I did the same thing

I did the same thing initially.

I have a user cert on my machine and root cert on the Juniper IC.

When i tried connecting to the SSDI, I get a Error saying " the cert required to join this SSID is not available on the machine"

Hence, i was wondering if any certs are required on the WLC.

You should have a user cert

You should have a user cert and a root    CA cert on client's pc and AAA server.

Search how EAP-TLS works on juniper server.
