Sorry for the delayed response; I know I've seen this message before. I believe it had something to do with endpoints configured in a manner keystone did not expect. Can you paste the full backtrace from the logs, and if it appears to be related, your keystone endpoint-list?<br clear="all">

Hi<br>
  I am installing openstack on ubuntu 12.10 beta2 with precise-updates/folsom repo , after sync keystone database, then these parameters in ~/.bashrc<br>
<br>
export SERVICE_TOKEN=admin<br>
export OS_TENANT_NAME=admin<br>
export OS_USERNAME=admin<br>
export OS_PASSWORD=openstack<br>
export OS_AUTH_URL=<a href="http://10.211.55.17:5000/v2.0/" target="_blank">http://10.211.55.17:5000/v2.0/</a><br>
export SERVICE_ENDPOINT=<a href="http://10.211.55.17:35357/v2.0/" target="_blank">http://10.211.55.17:35357/v2.0/</a><br>
<br>
when I add keystone users by "keystone user-create --name admin --pass openstack --email <a href="mailto:admin@foobar.com">admin@foobar.com</a>" or "keystone user-list", I got string indices must be integers, not str, is there any solution? My settings exactly the same as the wiki <a href="http://docs.openstack.org/trunk/openstack-compute/install/apt/content/ap_installingfolsomubuntuprecise.html" target="_blank">http://docs.openstack.org/trunk/openstack-compute/install/apt/content/ap_installingfolsomubuntuprecise.html</a><br>
