Thank you Rob. Now glance image-list is working fine with adding "insecure=True" to glance-api.conf and glance-register.conf below keystone_authtoken section. I'll also try the approach suggested by Rob for adding cafile path. I also set "insecure=True" for nova and neutron. Nova is working fine with SSL enabled keystone but neutron is still having weird issue. I am doing Google around it and I see lots of bugs related to the issue but nothing is clear if it's a bug or config issue, I am trying some workarounds but nothing seems working. When I try to do "neutron net-list", I can see error as "Authentication required" /etc/neutron/server.log shows following lines when net-list command is executed: 2014-04-15 03:50:34.947 24843 INFO urllib3.connectionpool [-] Starting new HTTPS connection (1): openstack-centos65 2014-04-15 03:50:35.045 24843 WARNING keystoneclient.middleware.auth_token [-] Verify error: Command 'openssl' returned non-zero exit status 4 2014-04-15 03:50:35.048 24843 WARNING keystoneclient.middleware.auth_token [-] Authorization failed for token 19ecd7820e37141d83f5ff7339da6656 2014-04-15 03:50:35.050 24843 INFO keystoneclient.middleware.auth_token [-] Invalid user token - rejecting request Neutron net-list --verbose output is attached. Please let me know your inputs. Regards, Devendra Gupta On Mon, Apr 14, 2014 at 6:32 PM, Rob Crittenden <rcritten(a)redhat.com&gt; wrote:
