I've been looking in the diff of the pam source package for the parameter causing the privilege drop, but i've not been able to find such parameter. I looked for "drop" and "privilege" and "root" and found nothing useful. Configure from "rules" file doesn't have options that apprents to drop privileges. I didn't saw any reference to this options in the documentation of PAM. So, what is different between pam in Ubuntu and in other distributions?
