We are working on migrating a Joomla based site to Concrete5. We currently use a few Joomla based add ons to integrate that CMS with Moodle. We are using an external SSO authentication successfully now with Concrete5, and are looking for a way to integrate with moodle. What we'd like to do is sync users from Concrete5 into moodle as well as pass the session token for automatic (sso style) login, without the need for the user to provide credentials. Can this be done with Concrete5?

On a side note, how do you pass the Session concrete5 creates to other web applications on the same domain?
