Hi,
If you're using Keycloak version 1.7 or later, you can create new
"firstBrokerLogin" flow and replace "Create User If Unique"
authenticator with your own implementation. You can create subclass of
IdpCreateUserIfUniqueAuthenticator and override method
"checkExistingUser" to not look for username at federation provider. It
can be done if you use:
context.getSession().*userStorage()*.getUserByUsername(username,
context.getRealm());
instead of:
context.getSession().*users()*.getUserByUsername(username,
context.getRealm());
Same for email checking.
In that case if you login with user "john" from external identity
provider, the authenticator won't try to find this "john" user in your
external federation provider, but just in Keycloak DB.
Is this what you are trying to achieve?
Btv. As pointed already, the keycloak username for user registered from
external IDP looks like "google.john" by default . You can change this
behaviour to use identity provider mapper for username, which allows you
to change the username template and remove broker prefix from that. So
Keycloak will treat this username as "john". In 1.9 we plan to remove
broker prefix by default and we will always just the username from
broker, because "first login flow" added in Keycloak 1.7 allow us to
easily resolve username conflicts. Corresponding JIRA is:
