I'm using 1.5 +. I have a big class, so I want to avoid having to manually enroll students. I'm also using 1.4.4 for another class, where the "no authentication" works great for having students create their own accounts.
The problem with my version 1.5 + is that students cannot create new accounts. "Invalid Login, please try again".
I think Vito LaVolpe encountered the same problem with 1.5 but there have been no responses to this: http://moodle.org/mod/forum/post.php?reply=119977
Is this a bug, should I report it, or is there a setting I'm missing somewhere?
