调研方向

No source file or test is named. Start by reproducing the capitalization mismatch through the user_external WebDAV backend and compare it with the database backend; done means differently capitalized usernames resolve to one user, one folder, and persistent admin edits.

描述

1. to develop bug

Affected apps

user_external

Steps to reproduce

log in multiple times to the same user via user_external (WebDAV) with different capitalization of the username
see different folders in the file system for the different capitalizations but only one user in admin/users
from admin/users try to edit parameters (display name / email) and see it getting overwritten back after refresh of the page

Expected behaviour

nextcloud should handle different capitalization of usernames and don't differentiate between them, as it does for users with the user backend "database"

Actual behaviour

strange issues occure as described in "Steps to reproduce"
