- When a user performs an `su` the effective UID changes but the bootstrap mach port does not, so that if container is running as `alice` from a GUI login session, it's possible to `su bob` and continue running container. While this doesn't pose a significant security risk as it's necessary for Alice to know Bob's password and manually enter it with `su`, this change closes the loophole by validating that client UID from the caller's audit token matches that of the API server.
