Abstract: In transferring a user application from an original user environment to a new user environment by dragging and dropping a graphical image representative of the user application, a new object or "shadow part" is automatically created in the new user environment with the same attributes as the user application in the original user environment. The new object also inherits the characteristics of other objects in the new user environment. The new object may optionally be linked to the original user application so that setting changes in one user environment are reflected in the other.

Abstract: A method and system for maintaining a secure association between a client and a server in a distributed computing system by computing a session identifier as a function of a Kerberos-based authentication ticket. The session identifier is independently derived or verified by the client and the server upon a first request by the client to the server, and each subsequent request by the client to the server is tagged with this session identifier to provide a reliable security association.
