Hi, I want to integrate an external service with keystone, in a way that only an authorized user in keystone could make access to that service. In the simplest form, consider it as a web service which receive the user's request and return a specific feature of his/her instance. Surely, users should be unable to see other's instance specifications, and must be authorized in the keystone. What do you think is the best way of performing this scenario? Thanks, Reza -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack/attachments/20140417/70078766/attachment.html>
