Dear all, The background is I have already installed all the openstack components on RHEL 6.1. Nova and Glance configured well, and can boot up normally. Keystone server also configured and boot up normally, while when I type the cmd as below, weird things happened. [root at kapi-r11 keystone]# keystone --token 8a47fd17e8950d483ea7 --endpoint http://127.0.0.1:5001/v2.0role-list string indices must be integers, not str Have you ever encountered the issue I met? Any keystone client cmd could not work well. I did some investigate on the keystone client code, but haven’t found suspected issue. Is it related with RHEL or python version?
