ldapsearch equivalent with Net::LDAP

I am trying to do the equivalent of this search:

     ldapsearch -x -LLL -b "dc=ldaphost,dc=mydomain,dc=com" uid

Here is one of the many variations I tried:

     use strict;
     use Net::LDAP;

     my $ldap=Net::LDAP->new("ldaphost.mydomain.com") or die "$@[EMAIL PROTECTED]
";
     my $mesg=$ldap->bind();

     if ($#ARGV<0) {
             $mesg=$ldap->search(
                     base=>"dc=ldaphost,dc=mydomain,dc=com",
                     attrs=>["uid"]
             );
     print $mesg->entries(),"\n";
     }
     else {
     }
     $ldap->unbind();


I am just starting so my code is incomplete but it should be enough  
to get something. However, I get nothing, not even an error. Can  
someone see what I am doing wrong? TIA.
