This is a difficult thing to achieve if you permit shell
access from your menu. You need to do it something like
what vsnl used to do for shell accounts.
Have a look at a shell script called "1bbs" ... this is a
very old program, don't know if it is on the net now ... I
can mail you a tarball if needed.
You should not permit su entries, since in su the $USER is
still the original user whereas "whoami" is root/ other
user. There is no login process or re-reading of .bashrc.
If somebody does su to this user, then just send him back
to his territory by adding something like this script to
be called from the first line of .bashrc:
#!/bin/bash
WHOISIT=`whoami`
if ! [ "$USER" = "$WHOISIT" ]; then
echo "You are treading on forbidden territory .."
su $USER
fi

Sub : No password login as user LOST #116
Fed up of typing password for every login as an user on stand-
alone boxes ? Edit /etc/login.defs. NO_PASSWORD_CONSOLE field
should have tty names ( e.g. example below permits no password
logins for tty4,tty5 and tty6):
NO_PASSWORD_CONSOLE tty4:tty5:tty6
