I have done this once on a un*x host, using Authen::Smb.
There are propably better ways if you are on a NT host, but anyway, some code: 
use strict;
use Authen::Smb qw(NTV_NO_ERROR);
my $pdc = "primary";
my $bdc = undef;
my $nt_domain = "DOMAIN";
....
....
sub password_ok {
  my ($username, $password) = @_;
  my $r = {};
  my $authResult = Authen::Smb::authen ($username,$password, $pdc, $bd
+c, $nt_domain);

  if ($authResult == $Smb::Authen::NTV_NO_ERROR) {
    if ($r = $mondb->get_user_data($username)) {
      return $r;
    } else {
      return {error=>"user not authorized"};
    }
  } else {
    $l->log("E", "User [$username] not authenticated with error level 
+$authResult: $smb_errtext{$authResult}");
    return {error=>"user authentification error"};
  }
  return undef;
}
