[keycloak-user] Some questions about user authentication with external IDP

We are planning on using Keycloak to authenticate users in our environment. There will be multiple sources of user logins. 1. Local to Keycloak 2. Using a Federation provider to pull accounts from on a one time basis (The first time the user logs in they will authenticate using the p/w in the Federation server, and subsequent logins will occur entirely in Keycloak) 3. Using a third party IDP (Like Microsoft/ Google/ etc.) But the initial source of these accounts might be local in keycloak. I of course can do #1, and know how to do #2. For #3 I have the external 3Rd party IDP working. But what we would like to have is this: 1. A user goes to a form in which they enter the username only. 2. If the user is new, it asks them to create an account 3. If the user is new, but we know the login to be associated with a third party IDP, we go there, and link the account. 4. If the user is not new, and if they are linked to third party IDP, it automatically loads that IDP page without having to pick that login. Here is the workflow we are thinking. An admin adds a list of accounts (either csv, or somehow else) into keycloak, but it says that all these accounts need to be authenticated by some third part IDP. So when a user logs into Keycloak and enters their password, it automatically redirects the user to the 3rd part IDP and then associates the local keycloak login with the IDP without having to do too much.
