Hi Danny:
I'm just a teacher, but also the system admin for our Moodle....
Doing account creation through LTI keeps it simple for the consumer system, but makes a huge mess in Moodle and creates multiple accounts for each user....I'm thinking there might be a setting under Authentication settings where you can lock user profile fields to help prevent duplication and to tie the accounts together...
Will have to test after the holidays, and will report back what I figure out....if anyone knows how to tie together LTI accounts with existing user accounts in Moodle, please share since this will help a lot of people!!
