L in LDAP stands for lightweight so server resources and bandwidth are (generally) no more problems since decades.

L*

I'm getting a failure to bind, either of the anonymous or non-anonymous kind. Perhaps I chose the wrong LDAP server. I guessed what it was on the basis of a Google search where the suggestion was to do an nslookup.

nslookup -type=srv _ldap._tcp.domain

nslookup -type=srv _ldap._tcp.domain.tld (?)

I got many replies, I chose one that sounded (phonetically) like it looked geographically compatible with my location in my domain.

There's no error at the time of bind but the bind error occurs when I try to execute the search.

script:

#!/usr/bin/perl

use strict;
use warnings;
use Net::LDAP;

my $ldap_server = "svlitdc1.shoretel.com";
my $ldap = Net::LDAP->new($ldap_server) or die "$@";
my $mesg = $ldap->bind ('', password => '', version => 3) or die "FATA
+L ERROR: LDAP bind did not succeed: $!\n";
my $username = "tienle";
$mesg = $ldap->search (base   => "c=US", filter => "(&(sn=" . $usernam
+e . ")(o=ShoreTel))");
$mesg->code && die $mesg->error;
foreach my $entry ($mesg->entries) { $entry->dump; }
$mesg = $ldap->unbind;
print "Done!\n";
