we use limits.conf to control the max no. of user login , users are only allow 2 login at the same time , now if I want when the user attempt to login the third session , then the system will prompt to ask the user kill the previous session or not , can advise what can i do ? thx

You can check this in the user's shell initialization script (like .bash_profile).
This will require to have .bash_profile read only for user.
