Also, pay careful attention to the file pathnames in the debug output 
and make sure you're editing the same file. A common problem is editing 
files in /etc/raddb but the server is reading files some other location.

For example your debug log shows this:

/usr/local/freeradius-server-2.2.0/etc/raddb/clients.conf

Is that the file you're editing?
