Who says 4294967294 is out of range?
# grep tstuser /etc/passwd
tstuser:x:4294967294:10::/:/bin/bash
# su - tstuser
-bash-3.2$ id -a
uid=4294967294(tstuser) gid=10(wheel) groups=10(wheel)
-bash-3.2$ touch /tmp/x0
-bash-3.2$ stat /tmp/x0

Looks good to me! The file just created has an ownership with the right
uid.
