Re: [openstack-dev] [kloudbuster] authorization failed problem
Hi, Akshay, Just curious, how do you find KloudBuster so far? Does it do its job and fit your needs? ☺ Thanks very much!

Can you provide the output of "keystone service-list"? We'd have to know a bit more about what you have been doing: how did you install your openstack, how did you install kloudbuster, which kloudbuster qcow2 image version did you use, who did you run kloudbuster (cli or REST or web UI), what config file have you been using, complete log of the run (including backtrace)... But the key is - you should really have a fully working openstack deployment before using kloudbuster. Nobody has never tried so far to use kloudbuster without such basic service as cinder working.
