Hello,

Please guide how to prevent multiple user to be logged in at a time using a user id ?

I searched the internet and found some ways but somehow they do not work in these situations:

If javascript in brower is turned off.
If user do not click logout and directly close brower.

Please suggest me some way.

thanks
