This IBM® RedpaperTM publication provides an example of a solution to synchronize an IBM RACF® user ID, password, and password phrase data between IBM z/OS® and IBM z/VM® systems, or just between z/VM systems. Topics that are covered are the installation and customization of IBM Tivoli® Directory Integrator, IBM Tivoli Directory Server, and RACF. Using this basic infrastructure, a sample Tivoli Directory Integrator configuration is presented, which allows for a flexible and extensible means for synchronizing RACF information.
