Single login for multiple clients in Joomla! 1.0?

Before Joomla! 1.0.8 due to a problem in the session implementation it was possible to login with one username simultaneously multiple times. This was corrected in Joomla! 1.0.8.

In Joomla! 1.0.8 a more secure session management was introduced which made it impossible to use the same login account more then once at a time. However, a 'hidden' feature was implemented: "demo site" which allows multi-login with the same account.

You can allow a group of people to access your website all at the same time with the same username/password combination. In order to accomplish that you'll need to change the var $SITE value in /includes/version.php from 1 into 0.

/** @var string Whether site is a production = 1 or demo site = 0 */
var $SITE = 1;

Note: This hidden feature is NOT present in Joomla! 1.5.
