[one-users] sunstone nil

Hi,

We are testing ON4.6 here in Fermilab
and sunstone produces the following error right after we start sunstone
as shown in C far below.

My guess is as follows:

The error message  A originates from another message B
A : NoMethodError - undefined method `call' for nil:NilClass:
B:  /usr/lib/one/sunstone/sunstone-server.rb:470:in `GET /:pool'

and B is found in   /usr/lib/one/sunstone/sunstone-server.rb
get '/:pool' do
    zone_client = nil

    if params[:zone_id]
        zone = OpenNebula::Zone.new_with_id(params[:zone_id].to_i,
                                            $cloud_auth.client(session[:user]))
        rc   = zone.info
        return [500, rc.message] if OpenNebula.is_error?(rc)
        zone_client = $cloud_auth.client(session[:user],
                                         zone['TEMPLATE/ENDPOINT'])
    end

    @SunstoneServer.get_pool(params[:pool],
                             session[:user_gid],
                             zone_client)
end

My guess is, zone_client is still nil in @SunstoneServer.get_pool
and the reason might be not properly setting up ZONE in our configuration.
I could not find what to do about ZONE in ON manual.

Please point us at the right direction regarding this error.
Thank you.
