You really can't do much with Win32::Lanman and AD, as you are only really using NT funtion to achieve what you want, so there's no control over anything purely Win2K/AD related. You really need to use Win32::OLE to do what you're trying to. Here are a couple of user modification sibroutintes that I use;

sub ad_modify { # To change a single value in AD

use Win32::OLE;

my $dn = $_[0]; # The object DN
my $attrib = $_[1]; # The attribute to change
my $value = $_[2]; # The attributes new value

my ($object);
    
$object = Win32::OLE->GetObject("$dn");

$object->{$attrib} = "$value";

$object->SetInfo; # Don't forget to set the values
}

sub ad_get_attrib { # For returning Attribute Values....

use Win32::OLE;
    
my $dn = $_[0]; # The object DN
my $attrib = $_[1]; # The attribute in question
    
my ($object,$result);
    
$object = Win32::OLE->GetObject("$dn");
    
if ($object->{$attrib}) { # If this Attribute actually exists....
    $result = $object->Get("$attrib");
}
    
return $result;
}

sub ad_search { # To search AD and return a pre-determined value

use Win32::OLE;

my $search_base = $_[0]; # This is the base for our searches 
my $filter = $_[1]; # This is the valid LDAP filter that we will be ap
+plying
my $attribute = $_[2]; # This is the attribute that we will be returni
+ng
my $search_scope = $_[3]; # This is the scope for our search to follow
    
my ($conn, $res, @result, $succ_search); # Variables that we are using
+ as we go
            
$conn = Win32::OLE->new('ADODB.Connection'); # New connection
$conn->{Provider} = "ADsDSOObject"; # OLE provider
$conn->Open;
$res = $conn->Execute($search_base . $filter . $attribute . $search_sc
+ope); # This is our search
    
if ($res->EOF) { # If we have found 0 records that match our search
    $succ_search = 0; # Set our no records found item and return it
} else {
    $succ_search = 1; # So our records found item
    $res->MoveFirst; # Go to the first record
    while (not $res->EOF) { # Whie we still have records
        push (@result, $res->Fields(0)->Value); # Push them to our arr
+ay
        $res->MoveNext; # Go to the next one
    }
}
    
return ($succ_search, @result); # Return our success and our array of 
+results
}

You could use a mix of Win32::OLE and Win32::Lanman::NewUser to achieve that you want (Win32::OLE will also allow you to move objects to new containers), but I'd suggest doing a bit of research and using Win32::OLE to do the whole lot.
