Hi Community,

I know Keycloak can work well with LDAP as User Federation. May I know how to implement that with an external API?

The workflow is as follows:

Client sends a request to Keycloak.
Keycloak checks the username: If it's a new user for Keycloak, Keycloak tries to authenticate bu visiting an external API endpoint. If it's an existing user for Keycloak, Keycloak will authenticate directly.

Thanks in advance!
