Only Once! Premium Edition for Joomla 1.5.X

Version 1.6.1
For more information see here.

Also available as Business Edition.

An authentication plug-in that prevents multiple log-ins by the same user credentials, for both frontend and backend. A useful tool for websites that share or exchange potentially sensitive information amongst its registered users.
User needs to either sign off the first session, or wait until the first session has expired.
Super Administrators can always have multiple log-ins.

With this premium edition, specified user groups can be allowed multiple log-ins.
Install or upgrade via Joomla! backend.

Requirements: Joomla! 1.5.26 or later. PHP 5.

Basic install, upgrade and setup instructions are in the documentation that comes with the download package.
Configuration overview: see here.

Supported languages: Front-end: configurable. Back-end: English.

Authentication and user plug-ins can be critical. The use of additional 3rd party (i.e. additional to a standard Joomla! install) authentication and user plug-ins may turn the Only Once! software partly or totally ineffective, meaning that it will not - or only partly - perform the tasks for which it has been designed. In order to avoid disappointment, we recommend that you always test the Freeware Edition before purchasing a commercial edition.
The Premium Edition does not support user log-in by email address.
