Abstract
A mechanism is disclosed for enabling an attribute provider service (APS), which provides access to one or more attributes, to control access to the attributes at the attribute level. In one implementation, a request is received, which specifies a particular attribute that is desired to be accessed from an attribute repository. In response to this request, a policy that applies to the particular attribute is accessed. The policy is then processed to determine whether access to the particular attribute is to be allowed or denied. With the above mechanism, it is possible to control access to attributes at the attribute level rather than at the service level. Because access control is exercised at such a low level, an administrator can exercise much tighter and precise control over how attributes provided by an APS are accessed.
