I just created a new user field in my form named UID and marked it required.
Now if I click anywhere on site administration it redirects me to
edit.php?id=2&course=1
and asks me to update UID and when I try to do it, it says:
Forbidden You don't have permission to access /user/edit.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument
to handle the request.
