I am in the process of linking my moodle site to an external database. Each user will therefore require a unique ID Number for this to work properly. However each student has the ability to edit this ID Number when they click on "edit profile" which would enable them to change their ID Number to that of another student and consequently cause issues.
I cannot see any option in the permissions to disable this option without disabling the entire "edit profile" for student accounts.
Does anyone have any ideas of how this potential issue can be avoided?
