解決方法

Swift のプロキシーサービスの設定ファル（ /etc/swift/proxy-server.conf ）で、[filter:keystoneauth] や [filter:authtoken] セクションが認識されていないことが原因であるため、設定ファイルでセクションがコメントアウトされていないか確認し、コメントアウトを解除する。

[root@controller tmp]# vi /etc/swift/swift.conf
※ コメントアウトされている
# [filter:keystoneauth]
# [filter:authtoken]
↓
コメントアウトを解除する
[filter:keystoneauth]
[filter:authtoken]
