duplicate email addresses for backend and frontend users
0%
Description
For backend and frontend users, it is possible in current TYPO3 systems to create different users with the same e-mail address.
In my opinion, it should not be possible to create a new user with an e-mail address that is already in use. I think it is very useful to check whether an e-mail address is already in use in the system when creating or changing it. Ideally, a JSON request should check whether this e-mail is already in use before it is saved.

hey steffen!
thanks for creating the issue. Especially for fe_users it is a valid usecase to have multiple records, even with same usernames. imagine having 2 sites with different registrations.
regarding be_users the email address is optional and therefore no need to have a unique check.
of course it is also a usecase to have a unique check. for the backend you can use 'eval' => 'nospace,trim,lower,unique', in the TCA config.
as the core won't change the behavior, I am closing the issue. feel free to contact me on slack to discuss it if you got further input.
