[one-users] OCCI Interface - HTTP commands

Both the OCCI client and curl seem to work fine...
<COMPUTE_COLLECTION>
<COMPUTE href='http://ccmanager.dyndns-work.com:4567/compute/129'
name='MyCompute'/>
</COMPUTE_COLLECTION>
And in fact the problem must or should be of authentication, or at least,
there should be, since I am not trying to get the information from the
"user" that created the VM. How is the authentication performed in the HTTP
commands?

I think the problem is the authentication. Would you mind to try using
the OCCI client provided with OpenNebula or curl?
$ occi-compute --url http://localhost:4567 --username <user>
--password <pass> list
or
$ curl -u <user>:<sha1_pass> http://localhost:4567/compute
You can get the sha1_pass using oneuser list.
