There are two easy ways to do this. Method number one is a batch file.

# assume $rs is recordset of usernames and passwords
open(BAT,">nt.bat");
while(!$rs->EOF) {
    print BAT "net user " . $rs->Fields("username")->value . " " . $rs
+->Fields("password")->value . "\n";
}
close(BAT);
system("nt.bat");

Or, you can use Roth's Win32::AdminMisc module. In that case:

# assume $rs is recordset of usernames and passwords
while(!$rs->EOF) {
    Win32::AdminMisc::SetPassword('DomainServer', $rs->Fields("usernam
+e")->value,$rs->Fields("password")->value);
}

Not putting them into the DB via cleartext would be a bit harder. How are they getting into the DB? If it is over a web-page, use SSL to put them in the DB. However, going from the DB to the PDC is a bit more problematic. It can be done, but I would not want to do it. I would take the cynide pill at that point.
