Fwd: SSL issues

13 May 2010

      Hi,

I am using a radius-openldap-EAP/TTLS|EAP/PEAP scheme and often I've got the
following error from a Windows 7 client trying to connect using EAP/PEAP.
Client lacked CA cert, but I've found clients that are able to import it.
Finally client connected using EAP/TTLS with SecureW2. But I wonder if there
was a problem with the client or there are a misconfiguration or a failing
certificate. Below my data, thanks in advance!
