#25617: Disallow usernames that differ only in case in UserCreationForm ------------------------------------------------+------------------------ Reporter: timgraham | Owner: nobody Type: Cleanup/optimization | Status: new Component: contrib.auth | Version: master Severity: Normal | Keywords: Triage Stage: Unreviewed | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | ------------------------------------------------+------------------------ Most applications don't treat user names as case sensitive. While we can't treat usernames as case-insensitive everywhere in Django due to backwards compatibility (#2273), by using `username__iexact` when checking for uniqueness of new usernames in `UserCreationForm`, we can at least prevent the creation of new usernames that differ only in case from an existing one. This protection won't cover creating a user in the shell or through the `createsuperuser` management command, but I don't think this is critical.
This wouldn't affect any usernames that already exist, and users will still need to login with the same case that they register with. -- Ticket URL: <https://code.djangoproject.com/ticket/25617> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
