Stopping auto enrollment

Joomla 1.5.23 Moodle 2.04+
Fresh install and all working well (excellent documentation).

I've set the course with an enrollment key. From the Joomla side when you ask to be enrolled into the course it does (no enrollment key asked)
I know the enrollment key is for self enrollment and Joomdle is using the user in Moodle to do a manual enroll so I've remove the function moodle_enrol_manual_enrol_users from the service Joomdle in Moodle BUT Joomla users are still automatically enrolled when they select the course.

Is there some other function I need to remove?

Thanks for any advice.

Hi.

I guess you enabled "self-enrolment" enrol method, but with a key.

And the you have in Joomdle, the "Enrol me" button, which auto-enrols the user with no key.

To solve it, I think you need to set "show enrol button" to No, and "show go to course button" to yes.
This way, user will be trasnfered to moodle course without enroling, and will be asked to enter the key to enrol.
