switching SAIO system to SSL: cannot start proxy-server (socket-error permission denied)

I have a working SAIO system configured to use regular HTTP. I need to switch it to use HTTPS.
I made changes to the config based on the guidance here:

http://docs.openstack.org/trunk/openstack-object-storage/admin/content/part-i-setting-up-secure-access.html

and further troubleshooting guidance about setting default-swift_cluster here: https://answers.launchpad.net/swift/+question/162268

Problem:

When starting the proxy server I get this traceback:

Traceback (most recent call last):
  File "/usr/local/bin/swift-proxy-server", line 7, in <module>
    execfile(__file__)
  File "/home/saio/swift/bin/swift-proxy-server", line 22, in <module>
    run_wsgi(conf_file, 'proxy-server', default_port=8080, **options)
  File "/home/saio/swift/swift/common/wsgi.py", line 128, in run_wsgi
    sock = get_socket(conf, default_port=kwargs.get('default_port', 8080))
  File "/home/saio/swift/swift/common/wsgi.py", line 77, in get_socket
    family=address_family)
  File "/usr/lib/pymodules/python2.6/eventlet/convenience.py", line 40, in listen
    sock.bind(addr)
  File "<string>", line 1, in bind
socket.error: [Errno 13] Permission denied

WORKAROUND?... I can start the proxy server as root without any errors. But when I try this (to reset the default ADMIN_URL and then add a new admin user) I get another error:

saio@swift-saio-0:/var/run/swift$ sudo swauth-prep -K swauthkey -A https://127.0.0.1/auth/
Auth subsystem prep failed: 403 Forbidden

So I'm stuck mucking through a SAIO conversion from http to https. I've exhausted google on this one. Can anyone help?

P.S. To convert SAIO to https, do I need to run the resetswift script? I did not do that. (I did run remakerings successfully).
