phpScheduleIt Authentication Plugin for Joomla 2.5

I need an Authentication Plugin for phpScheduleIt for authenticating Users of my Joomla 2.5 system (single sign-on solution). phhpScheduleIt already providers LDAP, Wordpress and Drupal Authentication Plugin but non for Joomla. The goal is that users, when they are logged in into Joomla 2.5, don't have to re-authenticate when they click on a link where the phpScheduleIt Site (it's wrapped in an internal zone of the Joomla site). Joomla and phpScheduleIt is Open-Source, you can find the files here: - Joomla 2.5: [login to view URL] - phpScheduleIt: [login to view URL] You will develop the plugin on your system locally and hand it over to me for testing/verification. No development will be made on our live-site. You only apply to this project when you have the adequate skills in PHP, MySQL and Joomla development. References in PHP coding and MySQL development are required to apply for this project.
