I'm getting the following error when running the keystone user-list command.

No connection adapters were found for '<ip-addr>:35357/v2.0/users'

I've searched the wiki, and Google, to no avail. Any help you can provide would be appreciated.

Can you provide more details, like version installed, configuration etc?

I apologize. I know better than to post a question like that without pertinent information. I've got CentOS 6.4 running on an IBM blade (HS21, I think), dual Xeon quad core 2.66 GHz processors, 16 GB RAM, 73 GB disk (RAID 1). CentOS is a minimal install, and I used a default partition layout.

This is a python error from a http library underlying OpenStack.

Essentially, somewhere in your configuration file or endpoints configuration, you will be missing a 'http://' or 'https://'. Find which option that is, add the appropriate protocol, and you will solve your issue.

Thanks for the push in the right direction. I had my endpoints set up with a public IP on an interface that was not configured to start at bootup. I used the os-endpoint directive, and pointed it to the internal url, and it worked. Next, I enabled the external interface, and that worked as well.

@ComputerConcepts, may I ask where you get that configuration working right?
