Thanks for your idea, indeed, this is the trick.

I added `override_fields = userdb_mail_crypt_private_password=%w userdb_mail_crypt_save_version=2` to the passdb config and it works

passdb {
  driver = passwd-file
  args = ...
  override_fields = userdb_mail_crypt_private_password=%{sha256:password}
