OpenIO swift deny host headers - reverse-proxy

Question

OpenIO 7.2.0.
I have an OpenIO with keystone (queens) auth cluster.
By default any user can configure his own acls and public url.
I would like to restrict user only for read and write in containers and objects.
Apparently deny_host_headers can do the job in proxy-server.conf but it not seems to be working -> nothing append.
I didn't find any "super admin" acls.
Any idea ?
My proxy-server.conf ->
# OpenIO managed

Answer 1

delay_auth_decision = False in authtoken section in proxy-server.conf file do the job.
delay_auth_decision : delay_auth_decision defaults to False, but leaving it as false will prevent other auth systems, staticweb, tempurl, formpost, and ACLs from working. This value must be explicitly set to True.
Now only files owners can view/create/edit containers/objects -> ACLs and sharing won't works.
