"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."

authd or identd has to be enabled on the CLIENTS, and its a completely untrustworthy system. the user information is sent in cleartext with no validation, and if the remote client is under someone elses control they can install a authd/identd that replies with anything they wish.
in centos6, at least, to install and enable authd, do...
# yum install authd .... # chkconfig auth on
