Thanks for the reply. My puzzle here is : I create containers & objects by my own, why other users can access them ? As mentioned in your article[1], the domain " sahara_proxy" is created by user "admin" in project "openstack". But I'm working under user "demo" in project "demo", and other people are in other project with other users. Thanks. -chen -----Original Message----- From: michael mccune [mailto:msm at redhat.com] Sent: Thursday, June 25, 2015 10:16 PM To: openstack-dev at lists.openstack.org Subject: Re: [openstack-dev] [Sahara] Why Sahara request user to give username/password for accessing the job binary in Swift ? hi Chen, i agree with Sergey has said, also i have posted a small article[1] about how i configure proxy domains. i hope this may help clear the confusion surrounding this feature. regards, mike [1]: https://elmiko.github.io/2015/06/25/configuring-sahara-with-proxy-domains.html __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: OpenStack-dev-request at lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
