BZ #1130574 - Use effective value for admin password display

https://bugzilla.redhat.com/show_bug.cgi?id=1130574

The admin password does not display the correct value when a single
password is set for the entire deployment. This corrects it to show the
effective value, depending on single_mode setting.
