Can someone help me change my program to use a recurssive subroutine?
Basically the script takes a manger username as argument and find all directs
and indirects reports under him?
my (@alldn,@alldn2,@alldn3,@alldn4);
my $manager = $ARGV[0];
print "Employees reporting to '$manager' are:\n";
&getDep($manager);
sub getDep
{
my $dmgr = $_[0];

"<1>ERROR</h1>";;
$dc = $RootDSE->Get("DnsHostName");
query_ldap("<LDAP://" . $dc .
">;(&(objectclass=User)(Samaccountname=$dmgr*));displayname,distinguishedname;subtree",$objects);
while (!$objects->{EOF}) {
getdirectreports($dc,$objects->Fields("distinguishedname")->{Value});
$objects->MoveNext();
}
sub query_ldap {
my $ldap_query = $_[0];
my $error_num;
my $error_name;
my $RS;
my $Conn = Win32::OLE->new("ADODB.Connection");

(".Win32::OLE->LastError().")\n -> $ldap_query\n";
return 0;
}
$Conn->{Open} = "Perl Active Directory Query";
my $Cmd = Win32::OLE->new("ADODB.Command");
if (Win32::OLE->LastError() != 0) {
print "Failed creating ADODB.Command object

return 0;
}
$Cmd->{CommandText} = $ldap_query;

$Cmd->{Properties}->{"Page Size"} = 99;
$RS = $Cmd->Execute();
