You can set the maximum number of connections to EFT Server at the Site level. With multiple sites, this means that some Sites can allow more users than other Sites.
To restrict the number of user logins
In EFT Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the Site you want to configure.
In the right pane, click the Advanced tab.
Select the Max concurrent logins check box, then specify the maximum number of logins you want to allow to a user at any given time. If the box is cleared, EFT Server does not restrict the number of logins.
Click Apply to save the changes on EFT Server.
