Comment 1 for bug 1884067

Hi adding my understanding here regarding this bug, please let me know if i miss something:
With reference to this[1] i could understand that a regular user's response doesn't contain binding-opt,
but a admin do[2], so a regular user should be restricted with that filtering field.

reproduced in my single host env:http://paste.openstack.org/show/798593/
