Manage and control number of active user loggins

Even though client license says it is for 10 users there are some chances more than 10 users can access the system at the same time. I have faced this situation many times and we didn’t had a option to control No. of user loggins. 

To achieve and control the number of user loggins I have written a small and silly code segment which check number of active users logged to NAV database and then check it with the actual users allowed. Then next user will not allowed to access the system if the number of allowed users are exceeded with the current level.

Here goes the code,

Import this codeunit and other objects and then compile. 

Go to company information form and set the number of active users you want to have for your company and then go to Codeunit 01 and then modify it to call the “checkSession” function for every new loggin. Compile and save the code. 

So from next loggin this would work and if the number of set users are exceed with the current active users, then that loggin will not go through and will result in closing the application automatically. 

Setting number of active users in company information table will not do work because then client can change it anytime he want. I think you can figure out a way to avoid that or to modify this code accordingly. 

Thank you and Regards,
