Will %{original_username} set %d as well?

You could try using %{original_username} in SQL.

Or you can try removing the auth_username_format and instead

passdb {
  driver = sql
  args = ...
}
passdb {
  driver = static
  args = user=%Ln noauthenticate
# you can remove next line if you want to always normalize your usernames
  skip = authenticated
}
passdb {
  driver = pam
  args = ...
  skip = authenticated
}
