We used RADIATOR with Cisco WLC and Cisco AP in our WiFi architecture.
We just replaced RADIATOR with Cisco ACS 5.2 .
Few computers with Windows XP SP3 have this error :
Resolution Steps :
Most of the computers (hundreds of Windows XP and Windows 7) got no problem.
ACS says "it is a known issue that the XP supplicant sends an empty TLS message instead of a non-empty TLS alert message".
If it was a known issue, we would have this error for other computer but we don't have (fortunately )
Wireless profile is sent to computers using GPO so they trust ACS server certificate...
Do you know how to correct this issue on XP supplicant? I dont find this issue on Google
Thanks for your help,
One way to troubleshoot is to physically have one of the laptops and see if unchecking the box that validates the server certificate fixes the issue. I have seen the same issue as you are seeing before and I would like for you to verfiy that.
If that doesnt fix the issue then we will have to proceed to taking a wireshark of the client and running a few debugs on the ACS.
Thanks for your answer.
I cant physically have one of the laptops
I will try to contact one of the owners but I think they can't uncheck "validate server certificate" because WiFi profile is sent by GPO.
If I succeed to change this option, I will contact you again.
