Hello
I would like to limit the number of times a user can login into my portal.
Thus, if the user is currently logged in when he/she attempts to login again we
want to prevent them from logging in hence limit one login per user. Or if you know of the way to disconnect the first login and allow the second login.
For ex:
the user logs in on one machine then goes to another machine and logs in again while the other session is still active. I need to make it so when the second login attempt is made it is denied since there is already an active connection with that username and password.
