Seems like V3AuthenticationApi does not have an implementation for access key authentication so the invocation routes to the base interface which does not have any HTTP annotation. I implemented the missing feature and it works for my openstack setup. Here is the commit history for my fork [2]. Please let me know if this is the correct approach and if so, I can send a PR
