[keycloak-user] multitenant login with Keyclaok OpenID connect providers

[Marian Petrik]

Dear Keycloak team,


I have a multitenant keycloak setup with dedicated tenant realms. The goal is to have a single login page and pick the target realm automatically based on the domain in the user email. Can this be achieved in keycloak?


My idea is to create an extra LOGIN realm with keycloak OIDC provider for each tenant realm. Client would only use this single LOGIN realm. The issue is how to get rid of the realm selection and implement custom authentication flow. Is this the right way to do this?


Kind regards,

Maran Petrik
