    Set up the user ID

    In the installed security package, the user ID should be configured with a UNIX UID and a home directory. Under the covers, UNIX file systems identify users by their UID (not their username), so for any particular user, the same unique UID should be used on all systems that the user logs into. The home directory, usually /home/username , should be located in a file system that is separate from operating system files, so that users home directories can be carried forward whenever the OS file systems are replaced with new versions.
