You can limit access from the username with tcpwrappers, but this also
will affect the rest of your user base.
Also the identd protocol is not very secure, someone with root access to
a machine can modify the identd too
show that the user is someone else, or possibly the person you are
allowing in with that username. It is better to
do a combination of the both for more security. I suggest you get the
newest TCPwrappers and read the documentation.
