hey folks, I keep seeing this on the internet

"The user name lookup feature of TCP Wrappers uses identd to identify 
the username of the remote host. By default, this feature is disabled, 
as identd may appear hung when there are a large number of TCP connections."

but I cant seem to find out how/where to enable said feature.
