Thank you for responding but it is not about adding users
This is about what would happen if the user has not been added or created in Moodle but that username existing in the enrolment file and is synced by moodle?
Would it create that username or would it say something like "user not found and enrolment record skipped"?
this is through a scheduled task... which reminds me, is there a log to show automated scheduled enrolment task results?
