It causes Solr indexes to be duplicated. There should always be a single unique userID for a user. You can map the login username to userID by returning "user" in passdb and userdb lookups. If you want to preserve the login username in logs, you can use %{auth_user} in mail_log_prefix and login_log_format_elements.
