updating users only in passwd file

[Antoine Jacoutot]

Hi :)

I've search google but couldn't find any definitive solution about how to 
achieve what I need with cfengine.
Basically, I am looking for a way to update passwd files on all stations using 
cfengine. It works with no problem with the copy: command, but what I would 
like to do is to only add/update/delete passwd entries which UID is superior 
or equal to 1000 (basically, users entries, not root, bin, www.....).
Did anyone find a nice solution on how to to this ?

Thanks in advance.
Regards,

Antoine
