Except that a knowledgeable user will comment out the line from the
.bash_profile or .profile and no longer have this restriction!
A better approach is to write a script that looks up the user and his/her
information from a configuration file and decides on whether the user is
allows or not allowed to logon.
This script can then be used as the shell in the /etc/passwd file.
Something like this...(this is pseudocode..)
#! /bin/bash
if (/sbin/scripts/checkusr) then
exec /bin/bash
else
echo "Not allowed to login at this time"
exec /bin/false
endif
# /sbin/scripts/checkusr is the script you need to write to check if the
# if the currently logged in user is allowed to login at this time.
# Return true if user is allowed to login. Return false otherwise
