while (<PASSWD>) {
    my @passwds = split /:/, <PASSWD>;
}

Note that you've used <PASSWD> twice. This will skip the even-numbered lines of the file, not the odd-numbered. This is because you read a second line from the file each time inside the loop, splitting on that value. Therefore, your first line that is read from the file (read into $_ in the while() loop) is more or less being discarded.
