Dear all, in our openstack cluster, we would restrict the actions that users can do with security group and security group rules. Here's what we'd like to achieve: 1. Lock down security group (and rules) so that only admin (or tenant admin?) can modify them. 2. Add additional rules to the default security group. Can you please give me some advices on how to achieve these goals? Thanks in advance, Giusy -- --------------------------------------------------------------- " Considerate la vostra semenza: fatti non foste a viver come bruti, ma per seguir virtute e canoscenza " Dante Alighieri Divina Commedia - Inferno - Canto XXVI --------------------------------------------------------------- Giuseppa Muscianisi, Ph.D. CINECA - SuperComputing, Applications and Innovation Department Via Magnanelli 6/3, 40033 Casalecchio di Reno (BO) - Italy Phone: +39 051 6171 775 www.cineca.it
