[keycloak-user] Custom Identity Brokering and First login flow: prevent username edition?

[Rémy Grünblatt]

Hi,

I'm using a custom IDP and I have some trouble during the first login
flow, it redirects to a "Update Account Information" page (this is
fine), but you can edit the username in this. How to prevent this
behaviour? As the usernames are provided by the third party, I don't
want people to be able to change them.


Thanks,

Rémy
