How to Block Multiple Session of same user account

[haneefputtur]

I am wondering is there any way which will block one user from loging in from 2 locations same time.
Currently if user logged in from one booth , same user credential can be used in another booth. Both can contribute each other for the test.
Basically I am looking for something which will stop user from taking same test from different locations same time.
Thanks in advance

Please note that TCExam logs the IP address of the logged machines and prints them on the results, so you can easily verify if a question has been answered from a different IP location.
Additionally you can restrict the range of IP addresses allowed to take the test.

Hi,
Thanks for your reply. Actually my problem is I do not want a single user to be able to login from multiple machines (even within same network) same time. One User - One Machine ... Is there any option I can set ?
Once again thank you for your valuable support.

If you set to TRUE the K_CHECK_SESSION_FINGERPRINT constant in shared/config/tce_config.php, then the session can be protected from hijacking but it still possible to have multiple sessions for the same user.

If the machine used by the student breaks during the test, then the student can continue the test using another machine and the teacher can increase the available test time required for the transition. The IP address change is logged and printed on results.

Dear Nicolaasune,
Thanks for the reply. I already set this option. However still it allows me to login from different machines same time for same account .
I am using the version : 12.1.010 and is there anything i am missing?
