In the beginning of the cert documentation, it says: The Microsoft "XP Extensions" will be automatically included in the server certificate. Without those extensions Windows clients will refuse to authenticate to FreeRADIUS.
But I use a certificate authority, so later on in the documentation, it says: If you have an existing certificate authority, and wish to create a certificate signing request for the server certificate, edit server.cnf as above, and type the following command. $ make server.csr You will have to ensure that the certificate contains the XP extensions needed by Microsoft clients. How do I go about ensuring this? Do I have to request them to be added from the CA? - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
