blob upload fails with 400 when use_sas_auth_only=true

[grahamkenville]

I'm writing a script to upload largish files. When I specify use_sas_auth_only it fails with a 400 error (see below). This is with waz-storage (1.3.6).

Thanks!

#!/usr/bin/env ruby

# gem install waz-storage --source http://gemcutter.org
require 'waz-blobs'

file_to_upload = "test.txt"

# Works:
# WAZ::Storage::Base.establish_connection!(:account_name => 'test', :access_key => 'key-goes-here')


# Doesn't work:
WAZ::Storage::Base.establish_connection!(:account_name => 'drbackup',
                                         :use_sas_auth_only => true,
                                         :sharedaccesssignature => 'key-goes-here'
                                         )


container = WAZ::Blobs::Container.new(:name=>'rubytest')

fd = IO.sysopen(file_to_upload, "r")
stream = IO.new(fd)


puts "Uploading"
container.upload(file_to_upload,
                 stream,
                 'application/octet-stream'
                 )
