You may allow those users only one connection.
If you have Redhat Linux .. you must insert in :
/etc/pam.d/login
session required /lib/security/pam_limits.so
and must add in /etc/security/limits.conf :
@users - maxlogin 1
( "@" is for groups.. if you want for a specified user user within @ like
john - maxlogins 1
* fol all users but 0 uid
you'll find a help for this in /etc/security/limits.conf
