Hi, I'd like you to take a look at this patch for potential DocImpact. https://review.openstack.org/17693 Log: commit 2b1b59afade68da44e3a1e6f5fa1c5c9472591da Author: Henry Nash <henryn at linux.vnet.ibm.com> Date: Fri Dec 7 16:47:56 2012 +0000 Add support for user groups This initial change provides the support in keystoneclient to match the api specified in the blueprint. Keystone itself does not yet support these calls, so if you actually called these, then you would get an error from the server. However the changes should be benign in terms of other api calls.
