Open Stack

PKI tokens require certificates. Check to make sure that your Keystone installation created certificates and that you keystone.conf file points to them.

Subject: [Openstack] issue when I using PKI for token format


Hi,

I'm working under CentOS 6.4 + Havana, my keystone version is:
          openstack-keystone.noarch 2013.2.2-1.el6 @openstack-havana

When I run command "keystone user-list", I get error:
         Authorization Failed: Unable to sign token. (HTTP 500)

I can get error information in both "keystone-startup.log" and "keystone.log":
