-=========================
- Authentication and ACLs
-=========================
-
-Requests to the RADOS Gateway (RGW) can be either authenticated or 
-unauthenticated. RGW assumes unauthenticated requests are sent by an anonymous 
-user. RGW supports canned ACLs.
-
-Authentication
---------------
-Authenticating a request requires including an access key and a Hash-based 
-Message Authentication Code (HMAC) in the request before it is sent to the 
-RGW server. RGW uses an S3-compatible authentication approach. 
-
-::
-
-	HTTP/1.1
-	PUT /buckets/bucket/object.mpeg
-	Host: cname.domain.com
-	Date: Mon, 2 Jan 2012 00:01:01 +0000
-	Content-Encoding: mpeg	
-	Content-Length: 9999999
-
-	Authorization: AWS {access-key}:{hash-of-header-and-secret}
-
-In the foregoing example, replace ``{access-key}`` with the value for your access 
-key ID followed by a colon (``:``). Replace ``{hash-of-header-and-secret}`` with 
-a hash of the header string and the secret corresponding to the access key ID.
-
-To generate the hash of the header string and secret, you must:
-
-#. Get the value of the header string.
-#. Normalize the request header string into canonical form. 
-#. Generate an HMAC using a SHA-1 hashing algorithm.
-   See `RFC 2104`_ and `HMAC`_ for details.
-#. Encode the ``hmac`` result as base-64.
-
-To normalize the header into canonical form: 
-
-#. Get all fields beginning with ``x-amz-``.
-#. Ensure that the fields are all lowercase.
-#. Sort the fields lexicographically. 
-#. Combine multiple instances of the same field name into a 
-   single field and separate the field values with a comma.
-#. Replace white space and line breaks in field values with a single space.
-#. Remove white space before and after colons.
-#. Append a new line after each field.
-#. Merge the fields back into the header.
-
-Replace the ``{hash-of-header-and-secret}`` with the base-64 encoded HMAC string.
-
-Access Control Lists (ACLs)
----------------------------
-
-RGW supports S3-compatible ACL functionality. An ACL is a list of access grants
-that specify which operations a user can perform on a bucket or on an object.
-Each grant has a different meaning when applied to a bucket versus applied to 
-an object:
-
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| Permission       | Bucket                                                 | Object                                       |
-+==================+========================================================+==============================================+
-| ``READ``         | Grantee can list the objects in the bucket.            | Grantee can read the object.                 |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``WRITE``        | Grantee can write or delete objects in the bucket.     | N/A                                          |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``READ_ACP``     | Grantee can read bucket ACL.                           | Grantee can read the object ACL.             |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``WRITE_ACP``    | Grantee can write bucket ACL.                          | Grantee can write to the object ACL.         |
-+------------------+--------------------------------------------------------+----------------------------------------------+
-| ``FULL_CONTROL`` | Grantee has full permissions for object in the bucket. | Grantee can read or write to the object ACL. |
