Creating new Users

I'm currently developing a web application system, whereby the administrator will manually create users accounts. Before the account is created the administrator/User login with the administrative account go to the admin page, click create new user link enter all necessary details. During this process the new created user will be assigned a role "Technician".
After this process is complete the page automatically logs out the "admin" and log-in the new created user and this becomes a problem if i want to create two or more users because the system kicks out the "admin", meaning will have to login again as an administrator to create another user.
How do i make sure the system doesnt kick out the "admin" after creating a new user?
