PEAP-GTC on Win 7 and 8 platforms (LDAP authentication doesn't work)

Cisco Employee

Hi all!
Customer is using Open LDAP as directory services.

We're setting Cisco Wi-Fi network with following authentication scheme:

Wireless LAN Controller - Cisco ACS 5.3 - Open LDAP

According to the documents ACS - LDAP supports only EAP-TLS and PEAP-GTC methods.

We need to perform username/password authentication. It works good on Apple and Android devices. But id doesn't want to authenticate Windows 7 clients.

We're unchecking "Validate Servers certificate" in WLAN settings of Win 7 client, but it still doesn't work.

It seems, that Windows doesn't support PEAP-GTC method. Are there any workaround to solve the issue?

I might assume, that there could be some software plug-ins (supplicants) that can be installed on Windows and give support of PEAP-GTC. But in this case customer will face serious organizational issues of provisioning new devices.

Please advice!

Thank you!

In order to see PEAP EAP-GTC option on the client, you need to install EAP-GTC supplicant on the client machine.

Which supplicant would you recommend for Win 7?

You can use Cisco Anyconnect NAM module for Windows 7.

Hope this help.
