THis statement appears completely wrong: 
            $search = $ldap->search(base=>"samaccountname=>$user,cn=>U
+sers,dc=>us,dc=>megatrends,dc=
+com",filter=>"(objectClass=memberOf)");

Here is some code I wrote years ago - you can use this as a basis for LDAP search: 
use strict;
use Net::LDAP;

my $dc = 'my.domain.controller.fqdn';
my $user = 'DomainName\UserName'; # or 'administrator@mycorp.com';
my $passwd = shift;   #'Adminpasswd';

my $base = "dc=TopDomain,dc=com"; #
my $scope = "subtree";
my $filter = "(&(objectclass=user)(objectcategory=user))"; 

my $ldap = Net::LDAP->new($dc) or die $@;

my $rc = $ldap->bind(  $user, password => $passwd);
die $rc->error if $rc->code;

my $search = $ldap->search (
    base => $base,
    scope => $scope,
    filter => $filter,
    sizelimit=> 9999 # Does not seem to help...
    );
die $search->error if $search->code;

foreach my $entry ($search->entries) {
    $entry->dump;
}

$ldap->unbind;
