+ Role
+======
+
+A role is similar to a user and has permission policies attached to it, that determine what a role can or can not do. A role can be assumed by any identity that needs it. If a user assumes a role, a set of dynamically created temporary credentials are returned to the user. A role can be used to delegate access to users, applications, services that do not have permissions to access some s3 resources.
+
+The following radosgw-admin commands can be used to create/ delete/ update a role and permissions asscociated with a role.
+
+Create a Role
+-------------

+
+Add/ Update a Policy attached to a Role

+
+To add or update the inline policy attached to a role, execute the following::
+
