Hi Bozhidar,

Do you understand that if you are *not* using a self-signed (i.e. ACS
generated) certificate, you need "two" certificates to enable PEAP?

You will need to install the CA certificate (i.e. the Windows 2003 CA
certificate) as well as enroll for a certificate with the CA.

The first certificate enable ACS to trust the CA, and the second certificate
is what ACS will present to the client during the EAP SSL handshake.

HTH;
