Suppose the return result from subroutine query_LDAP and query_AD should be compared,but here the comparison not working.

i have no idea what is wrong here, please advice dear monks..

i have provided my source codes here, please assist..

sub query_LDAP {
$ldap = Net::LDAP->new( 'hostname' );
$mesg = $ldap->bind( 'uid=username,ou=xxxx,o=bbb',
                    password => 'secret'
                    );
$result = $ldap->modify( "uid=username,ou=xxxx,o=bbb", 
                            replace => {"name" => "star wars"} );
$result->code && warn "failed to add entry: ", $result->error ;
$result = $ldap->search ( base => "ou=xxxx,o=bbb",
                        filter => "uid=username"
                      ) or die ("Failed on search.$!");
foreach my $entry ($result->entries) {
my $LDAP_name= $entry->get_value( "name" );
print "Query Result from LDAP : ",$LDAP_name,"\n";}
$mesg= $ldap->unbind;}  # take down session


sub query_AD {
$ldap = Net::LDAP->new('hostname') or die "$0";
$mesg = $ldap->bind( 'cn=username,ou=somecontainer,DC=com',
                    password => 'secret');
$result = $ldap->search(base  => "ou=somecontainer,DC=com",
                          filter=> "cn=username"
                          ) or die ("Failed on search.$!");

foreach my $entry ($result->entries){
my $AD_name= $entry->get_value( "name" );
print "Query Result from AD : ",$AD_name,"\n";}
$mesg= $ldap->unbind;}  # take down session

if (query_LDAP() ne query_AD()) {
    print "not identical!!!!\n";}
    else{
            print "its the same\n";}
