To those of you experimenting with Joomla 1.5 or thinking of using it in the future, I have hacked the code to allow for front-end and back-end login to Joomla using the following onyen authentication web service created by Todd Lewis at: https://onyen.unc.edu/cgi-bin/unc_id/authenticator.pl
If any of you would like the onyen authentication code for Joomla 1.5, I hope to have it published soon, but if you can’t wait then just let me know.
In the near future I will also be implementing code to register users with a Joomla site using this same onyen authentication web service, so stay tuned.
