Please don't send more that one email, we heard you the first time.

This sounds like a permission problem. Make sure when you run your test
manually you do so as the same user and group radiusd is running as,
you'll find those values in your radiusd.cong file.

Also if your system is running SELinux check for the presence of AVC's
