What probably happens is that radiusd does a fork later, as all
unix daemon programs do. From the RA meta-data:

binfile* (string): Full path name of the binary to be executed
    The full name of the binary to be executed. This is expected
	to keep running
	 with the same pid and not just do something and exit.

Looks like "anything" is not suitable for radiusd. You can try
the lsb (i.e. /etc/init.d/...) RA.

Thanks,
