ldap ACS PEAP EAP-MSCHAPv2

Hi there !

I would like to know if there is a problem with a radius authentification with a Cisco ACS and PEAP (EAP-MSCHAPv2) using a Digicert wild card certificate ?

We are using cisco 5508 wifi controlers and a Cisco ACS 5.2.0.26, an Active directory 2012 and a Digicert wild card 2048bit.

And we are using the ldap fonction in the ACS.

In the ACS, Access Policies > Access Services > service-wifi-acs > Edit: "service-wifi-acs", Allowed Protocols, Allow PEAP. When I activate "EAP-MS-CHAPv2" ipads and androides are not working. And when I activate "EAP-MS-CHAPv2", I can't make Microsoft boxes work. I did try to activate all protocols with no success.

We are using a wpa2 enterprise, aes on the Cisco 5508 wifi controlers.

Any clues how to make work the radius/ldap with Microsoft boxes + ipads + androides ?

Thank you !
Chris

Hi craigbeck !

Thank you for the tip.

Well, now it has nothing to do with the certificate from what I understand.

I did upgrade the Cisco ACs from 5.2 to 5.5 and put it in "ad mode".

I was able to activate the mschapv2 without causing trouble to ipads/androides.

The Windows 7 are able to authenticate but I have to manually configure the conexion to force the usage of prompted user input so it wont use the local account of the open session on the windows box.

So now I'm searching to configure the ACS so I don't have to configure anything on Windows boxes. Some are saying it's not possible. :_(

Thank you again !

That's true. Windows will send the currently logged-in user credentials to authenticate by default. You have to turn that off manually if you want to prompt for alternative credentials.

If you deploy the WLAN profile via GPO you can turn this off on each Windows machine automatically.
