[keycloak-user] username to be used for importing users

[Leonid Rozenblyum]

Hello!
We're using 2 keycloak instances.
SP -> Keycloak (broker) -> Keycloak (Identity provider)

How can we configure the broker to create user names equal to the original
username from keycloak (Idp)? Now the new users inside the broker receive a
G-.... (long meaningless string)
username during the first log-in.

So if user logs in through Idp with login: 'hello' we would like user
'hello' be created in the broker

Thank you for advice.
