How would you expect user management to work if usernames are not unique?

Are you planning to differentiate users with identical usernames some
other way?

Kind regards,

I recommend : DON'T, because it is by default UserIdentifier, It is used to make UserLogins and you have to override a lot of builtIns to achieve what you are trying to do.

 

But if you still want to:

`username` validator is defined in AbstractUser Class, and inheritence flow is like: 

AbstractUser -> User

i believe only way to overide this validation is to create a Proxy Model

By using split fields. I've ran into this as well, as I want to allow the same
username per different domain - ya know, like emails.

I ended up with a choice to duplicate the data as a single database field or
ditch django.contrib.auth. I went for solving the problem at the form level
and not storing the username / domain in the custom user model, but storing it
as an email field that had to be unique.
