honest question: whose business is the name of a user who initiated a
connection??? identd is a horrible concept and elicits shrieks among
the security conscious. i do understand that you need it for this and
that, so install oidentd, which has a feature to return random user
names, but other than that, don't worry about it. ident is a hacker's
friend, not only because nmap can tell everyone who is running the
services behind your open ports. you don't want that.
