Before configuring WebSphere to use the local operating systems user registry, you need to know the user name (ID) and password that will be used by the application server as its own identity when setting up authorization policy and when authenticating to other application servers (for example, in a WebSphere Application Server Network Deployment environment). <br/> <br/> When using the Local OS user registry with WebSphere for z/OS, user name and password are not specified through WebSphere administrative facilities. Rather, the user name associated with the server is configured through the administrative facilities of the platform security product.

This user will be referred to as either a product security server ID, a server ID or a server user ID in the documentation.
