20100180329 | Authenticated Identity Propagation and Translation within a Multiple Computing Unit Environment - An authenticated identity propagation and translation technique is provided in a transaction processing environment including distributed and mainframe computing components. Identified and authenticated user identification and authentication information is forwarded in association with transaction requests from a distributed component to a mainframe component, facilitating the selection of the appropriate mainframe user identity with which to execute the mainframe portion of the transaction, and creating the appropriate runtime security context. The forwarded user identification and authentication information contains a plurality of sections with identifying information about an authenticated client end-user identity as known at the initial authentication component and a mask specifying a subset of the sections. The mainframe component generates a hash from the subset of sections specified by the mask and uses that hash as a lookup key to determine whether a local authenticated runtime security context already exists in a local cache for the client end-user initiating the transaction request. | 07-15-2010 |
