System Administrator's Guide/Moodle//Mahara Integration
The integration between Moodle and Mahara has been affectionately named "Mahoodle". It allows true single-signon between both systems - no password sharing required, and users' profile information is ported across. In addition, from Mahara 1.2, users are able to submit Mahara Views to Moodle for assessment (with a plugin for Moodle).
The best instructions for setting up the integration can be found in the PDF entitled "Mahoodle", which you can find attached to this wiki page. The instructions and screenshots are a little out of date, but the process works.
More up to date instructions and screenshots are available in the mahoodle-updated-en.odp and mahoodle-updated-en.pdf files attached to this wiki page. You should also read the original Mahoodle.pdf file to get more detailed explanations about the whole process.
