Imposing uniqueness of user names across tenants

[liorbalmas]

Hi
Can uniqueness of user names be imposed across tenants without customizing identity module?
Thanks

hi @liorbalmas

You need custom modules.

Do you mean I need to customize the module or to add some other module?

Can adding a unique index to the users table manually do as dirty workaround?

You can't, You need to use code to check if there is a username that already exists.
