Abstract

A method and apparatus for enabling a listening daemon in a client/server system to execute a specified task on behalf of a user. Upon receiving a user request, the listening daemon sets an environment variable in accordance with the user identity specified in the request and issues a system call to the operating system kernel to spawn the user task specified in the request. In response to the system call, the operating system kernel creates a new address space for the specified user task and creates a security environment for the user task in accordance with the environment variable before starting the user task in the new address space.
