CloWM S3Proxy Service
Description
Openstack is shipping with an integrated UI to access the Object Store provided by Ceph. Unfortunately, this UI does not allow fine-grained control who can access a bucket or object. You can either make it accessible for everyone or nobody, but Ceph can do this and much more. 👎 This is the backend for a new UI which can leverage the additional powerful functionality provided by Ceph in a user-friendly manner. 👍
