Uploading a file of users in domain context
- default sections for course stored in "sections" form element
- validation of courseID for selected course to confirm it is valid
Uploading a file of users in author or course context
- if users already exist, use user modification rules set by DC to check which user information fields can be updated
- aggregate any existing roles in current context with intended added role to evaluate user modification rules.
- validate proposed new section name for conflicts with group names and reserved names (none and all).
- for courses roles can be assigned for multiple sections (cc and st) excluded, unless uploader has section-specific 'cst' priv.
- role specified for each user in upload file can be custom role available to uploader.
- validate proposed role from field in uploaded file with permitted roles uploader can assign
&roles_on_upload() routine added - returns scalar (true is custom roles allowed, and array of permitted roles uploader can assign.
