MS PEAP supplicant easiest than ACU

On lab environment, I have a Windows XP SP2 using MS supplicant PEAP, a 350 NIC with Aironet client 802.11a-b-Wizard v14, an ACS V3.3 and an AP1100 with IOS release 122-15.XR2 altogether working fine.

I haven't had this configuration working using Cisco supplicant PEAP, even using the newest ACU version 6.4.05. Naturally, I took care uncheck "Use Windows to configure my wireless network settings" on

Windows XP Wireless Networks tab.

I read that PEAP on ACU correspond to check Host Based EAP (802.1x) and Dynamic WEP on Network Security tab. That was I did.

Debug shows the following messages:

Nov 13 19:47:41.010: dot11_auth_dot1x_start: in the dot11_auth_dot1x_start

Nov 13 19:47:41.010: dot11_auth_dot1x_send_id_req_to_client: sending identity request for 000e.84c4.ed17

Nov 13 19:47:41.010: dot11_auth_dot1x_send_id_req_to_client: Started timer client_timeout 30 seconds

Nov 13 19:48:11.010: %DOT11-7-AUTH_FAILED: Station 000e.84c4.ed17 Authentication failed

Could anyone give me a hand.

Thanks,

Re: MS PEAP supplicant easiest than ACU

It looks like that something wrong with the wireless adapter. After the AP receives an EAPOL start, the AP sends an identity request to the wireless client. However, the wireless client does not respond to the identity request.

One of the most common issue is that you need to enter a user name in the XP, but you fail to do so in 30 seconds.

Re: MS PEAP supplicant easiest than ACU

Ok, I need to enter a username, but unlike LEAP configuration, ACU didn't give us a chance to enter a username/password/domain on Network Security tab previously. So, I guess ACU should rely on machine credencial or open a screen asking for identity opportunely, like a successful windows XP PEAP supplicant does, but it doesn't occur. That is the point, no way to enter username.

Do you agree with me that ACU PEAP configuration is setuped checking "Host Based EAP (802.1x)" button,

and "Dynamic WEP" button on Network Security tab?

If so, why a login window doesn't show up?

Re: MS PEAP supplicant easiest than ACU

I got ACU PEAP supplicant to work. It was through a workaround, in my opinion.

The way to accomplished that was check the box "Use Windows to configure my network settings" on Windows XP Wireless Network Connection at the same time as check box "Use Selected Profile" on ACU.

A important detail in this scheme is that doesn't matter which SSID is added on Wireless Network Connection. Indeed, we can add a dummy SSID just for setup the authentication method ("Enable IEEE 802.1x authentication for this network" and "Propected EAP (PEAP)") and choose a Certification Authority.

My conclusion is forget ACU for PEAP supplicant purposes and use MS XP PEAP supplicant because this one is more intuitive, precise and coherent than ACU.

I would like to hear from you what you think about it.

Thanks,

Carlos

Re: MS PEAP supplicant easiest than ACU

Hi Carlos,

I'm glad that you solve your Problem.

I'm trying to setup PEAP with MS supplicant XP SP2, AP 1100 with IOS 12.2(15)JA, ACS 3.2.3, NIC intel PRO 2200BG that is CCXv2.

I want machine and user authentication.

I'm having problems with changing of vlans ip address as user login and logoff

Have you experencied this kind of problems?

Thanks
