Abstract:
1. A computer program product in a computer readable medium executable by a data processing system for authorizing access to a protected resource, the computer program product comprising: instructions for intercepting a remote procedure call for a remote routine of a Distributed Computing Environment (DCE) authorization service by an authorization plug-in associated with a second authorization service, wherein the authorization plug-in exports remote procedure call endpoints for the remote routines of the DCE authorization service, and wherein the second authorization service supports a standard-compliant authorization application programming interface; instructions for processing the authorization request in the authorization plug-in by calling application programming interfaces of the second authorization service; instructions for recompiling or reliniking a target application representing one or more protected resources to include program instructions from the authorization plug-in; instructions for directing calls within the target application to application programming interfaces of the DCE authorization service to be executed by the program instructions from the authorization plug-in; instructions for accepting a call in the authorization plug-in to a “dce_acl_is_client_authorized” application programming interface; instructions for authenticating the authorization credentials passed by the initiator to the target application; instructions for retrieving the privilege attribute certificate from the DCE EPAC structure; instructions for mapping a DCE Access Control List (ACL) manager Universally Unique Identifier (UUID) from the DCE EPAC structure to a resource manager in the second authorization service; instructions for mapping DCE ACL UUID from the DCE EPAC structure to a resource managed by the second authorization service; instructions for mapping the DCE permission set from the DCE EPAC structure to a permission set of the second authorization service; instructions for calling an application programming interface of the second authorization service to make an authorization decision based on the permission set of the second authorization service, the privilege attribute certificate, the resource, and the resource manager; and instructions for returning an indication of the authorization decision to the target application.
