Error in radius log

[LeRoy DeVries]

I am getting the following error:

Tue Dec 20 16:51:22 2005 : Info: rlm_exec: Wait=yes but no output defined. Did 
you mean output=none?

The portion of the radius.conf that reflects that portion is as follows:

exec {
		wait = yes
		input_pairs = request
	}

How do I correct it?
