More information:
I tried all three options for Authentication – First Broker Login – Create User if Unique
With “Alternative” I get the behavior below
With “Required I get "User with email xxx at gmail.com already exists. Please login to account management to link the account.” and the account is created without a link to Google
With “Disabled” I get “Invalid username or password” and the account is never created at all in Keycloak.
Thank you.

I modified the Keycloak code directly in the method you mentioned, recompiled the whole package, and attempted to use it. The issue now is that when I log in using a external Identity provider, and have a User Federation defined, I still get called in my user federation with the username that is from the IDP. Plus the login screen shows me a screen with “ACCOUNT ALREADY EXISTS” and an option to review the profile info or Link Google with existing account.
The account does not exist before starting the login process.
Thank you for all your help in getting this working. I am attempting to use 1.8RC3 BTW.

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: https://issues.jboss.org/browse/KEYCLOAK-2292

It looks like no matter which External IDP I use, it always checks the federation provider also which is not something that I think wants to be done. Is this a bug in the Keycloak software?
So it looks like one cannot do external IDP and federation at the same time. This should be fixed.

I think that’s a more general question about user account merging so maybe one of the core devs can chime in. However, I just want to clarify, you don’t want to query the federation provider at all when a user signs in with external IDP, right? In that case, you could modify the findByUsername() method to not create a user if the login is with a IDP. I’m not sure if it still exists in 1.7+ but the username used to be created as idp.email at provider.com<mailto:idp.email at provider.com> where the IDP is the username prefix.
Does that make sense / sufficiently address the use case?

This is working for me now. I created a service that listens on a port and implements the GET, HEAD and POST requests that are being made.
The one issue now is that integration with other Identity providers does not work now since it still calls my server with the username from the external provider. How can I tell Keycloak that when a user comes from an external Identity provider not to check the user Federation provider?
Thank you,

We just put up and blog post[0] and some sample code[1] on how to do this type of migration.

Hello Reed,
as you already wrote, you can write a federation provider that queries your
backend service via REST for user data.
Within the federation provider you can then import the user data
returned from the REST call.
This would work as follows - within the method:
org.keycloak.models.UserFederationProvider.getUserByUsername(RealmModel, String)
you call your backend REST service.
As a next step you create a new user with the given username
UserModel keycloakUser = session.userStorage().addUser(realm, username);
Then you copy all the user data from your backend into Keycloak's UserModel.
After that your backend user has a corresponding representation in Keycloak
with a reference to this federation provider (id) via the "userModel.federationLink" property.
The federation link will also be shown in the user page in the keycloak admin console.
As long as the federation link is in place keycloak will ask the federation provider
for the latest user data. Once you decide to cut the link to the federation provider you can
simply do userModel.setFederationLink(null). You could basically cut (or rather omit) the federation
link right after you added the user to Keycloak.
Keycloak has no link information after that anymore and it will only use the user data stored
in the Keycloak database for that particular user.
You also have the option to do that for all your users via:
org.keycloak.models.UserFederationProviderFactory.syncAllUsers(KeycloakSessionFactory, String, UserFederationProviderModel)
or just use on demand per User when he / she want's to login for the first time.
Cheers,
Thomas

Hi,
We are examining KeyCloak (It looks like it can do what we want), but we have the need to have an external lookup of accounts who are not in KeyCloak in an external database which is accessible via a REST call. I know about federation, but would prefer to only check the external datasource if the user is not in KeyCloak, but from then on have all the data “live” in KeyCloak and never refer to the external datasource again once the account is “migrated” into KeyCloak.
Can this be done with some modification of federation?
We do not want to add the user accounts directly into KeyCloak as there are many more there than will ever be in KeyCloak.
Thank you,
Reed Lewis
