+All of Fog's `openstack` options (`openstack_domain_name`, `openstack_project_name`, ...) are supported. This includes support for the OpenStack Identity v3 API:

+    knife[:openstack_username] = "Your OpenStack Dashboard username"

 If your knife.rb file will be checked into a SCM system (ie readable by others) you may want to read the values from environment variables.  For example, using the conventions of [OpenStack's RC file](http://docs.openstack.org/user-guide/content/cli_openrc.html) (note the `openstack_auth_url`):
 
     knife[:openstack_auth_url] = "#{ENV['OS_AUTH_URL']}/tokens"
     knife[:openstack_username] = "#{ENV['OS_USERNAME']}"
     knife[:openstack_password] = "#{ENV['OS_PASSWORD']}"
