I got a weird issue with the AD integrated account. Some of the AD accounts changed the username by themselves. It adds an underscore and 4 digits random numbers for some reason. It just happens by itself. The actual account in AD has no changes. I can’t find any way to correct it. I tried deleting the account in the Nextcloud interface but it won’t work since it’s an AD account. Does anybody get an idea how this happen from beginning? Like the account here. It used to be YLlamas but changed itself to YLlamas_7257.
