I can't run the script, because I don't have access to unix/linux at work. The first 3 columns are "root, encrypted pwd, 6445". The 6445 is to my understanding the days counting from 1/1/1970, i.e. 25 August, 1987. Is that not correct?
Update: I came to think, could it be that the machine has been installed from a backup tape or an image and hence inherits all this stuff?

Another question for me is that in the shadow file, there are the columns min and max password days to change, which generally, but not always, are from the default password policy. If these columns are empty, does it mean that these rules do not apply (that's what I think) or that the default policy applies, except for root?
