Why is Security Attribute important?
The Security attribute propagation is useful when you want to propagate the security attributes of the authenticated user specially the dynamic attributes like login time, logon location. Security attribute propagation makes the JAAS Subject based runtime more useful. When you use the Reverse Proxy Server, the originating attributes are very important, because they define the ACL of the originating caller through out the down stream system. For example, when you want to maintain the information about the originating caller identity, authenticated user strength, location and so on, we can use the security attribute propagation feature and add these attributes to the Subject that is propagated downstream.
