Hi. I’m looking for a way to move a few thousand user accounts to Keycloak. The system which currently holds the user data will be shut down after. If I understand correctly, this could be done with user federation (https://www.keycloak.org/docs/latest/server_admin/#_user-storage-federation) with a provider that stores all data in Keycloak’s database?
Some providers even import the user locally and sync periodically with the external store.
In the old system, the passwords were hashed with bcrypt. As far as I see, Keycloak doesn’t support bcrypt and a third-party plugin would be needed (https://github.com/leroyguillaume/keycloak-bcrypt). Is there a way around? For example, is it possible to import user data from federation upon login but take (and hash) the password as provided by the user?
