[keycloak-user] Multiple Social Providers for Single Account

At this moment, if you have Facebook and Google account and both have
same email address "foo at gmail.com" , you need to either:
1) Register user first with Facebook, which will create new user account
in Keycloak with email address "foo at gmail.com" and this account will be
linked with Facebook. Then you can link this user with Google in Account
Management UI. In this way, user with email "foo at gmail.com" will be
linked to both Facebook and Google and from this point he can login to both.
2) Manually register user with email "foo at gmail.com" and then link him
in Account Management with both Facebook and Google.
What you can't do ATM is to register user with Facebook first (like in
first part of flow 1), then logout and then try to register him with
Google. In this case user is not yet linked to Google, but user account
with email address "foo at gmail.com" already exists in Keycloak. So that's
why it fails because there is enforcement to have unique email addresses
I agree that it would be nice to have support for this flow. I think
when trying to SignIn with Google in case that user with this email
already exists, Keycloak should display screen with some message like:
"User with address foo at gmail.com already exists. Do you want to link
your account with this one?" . In case that user choose "Yes" he will
need to login into Keycloak via some different form. If user choose "No"
registration will be finished as failed. Support for this flow is a bit
tricky and IMO it won't be possible to do it in Keycloak 1.0.Final, but
probably somewhere later. What we can do in 1.0.Final IMO is just do a
small fix in UI that there is no exception message like
"ModelDuplicateException" displayed somewhere in UI, but instead some
more friendly message will be shown like: "Your email foo at gmail.com
already exists in Keycloak. Login first and then link your account with
