Prevent simultaneous login in web application hosted on WebSphere
===

I am using WebSphere Application Server V8. 
When I login to WAS admin console from one machine and at the same time attempt to login to WAS admin with same user credential from another machine, it displays the below message:

Another user is currently logged in with the same user ID. Select from the following options: 
•	Log out the other user with the same user ID. You can recover changes made during the other user's session.  
•	 Return to the Login page and enter a different user ID

How can I implement this in my web application hosted on WAS?
