Facing problem is configuring freeradius for eap-ts

[A.L.M.Buxey at lboro.ac.uk]

hi,

you are using Windows version of FreeRADIUS?  The certs will need
to go into a directory readable by the server - as in eap.conf
config file - ie wherever YOU want, that the server can read.
normally, and for sake of debugging sanity by anyone who helps
on this list, you'd use $RADDB/certs/  as per normal.

generation? Read any of the EAP_TLS HOWTO docs or check out the
freeradius site - or get a Linux copy of freeradius (just
fire up a decent live distro, install freeradius, grab
the certs and copy them to your windows machine). 
or, if you are a windows server user generally, generate
the windows certs on a windows server using the AD toolkit.
