I prefer using "as_struct" method to place all search results in one perl structure. Like this

#!/usr/bin/perl -w

use strict;
use English;
use Data::Dumper;

use Net::LDAP;
my $ldap = Net::LDAP->new("ldap://ldapserver.company.com") or die "$EV
+AL_ERROR";

my $mesg = $ldap->search(
    base => "ou=people,dc=company,dc=com",
    scope => "sub",
    filter => "cn=oracle*",
);

my $struct = $mesg->as_struct;
print Dumper( $struct );

So the output will be something like:

$VAR1 = {
  'uid=oracle8,ou=people,dc=fresenius,dc=de' => {
    'gidnumber' => [
      '4019'
    ],
    'objectclass' => [
      'shadowAccount',
      'posixAccount',
      'account',
      'top'
    ],
    'loginshell' => [
      '/bin/sh'
    ],
    'uid' => [
      'oracle8'
    ],
    'homedirectory' => [
      '/home/oracle8'
    ],
    'cn' => [
      'oracle8'
    ],
    'uidnumber' => [
      '3355'
    ],
    'gecos' => [
      'Oracle8 user account'
    ]
  },
  'uid=oracle7,ou=people,dc=fresenius,dc=de' => {
    'gidnumber' => [
      '4019'
    ],
    'objectclass' => [
      'shadowAccount',
      'posixAccount',
      'account',
      'top'
    ],
    'loginshell' => [
      '/bin/sh'
    ],
    'uid' => [
      'oracle7'
    ],
    'homedirectory' => [
      '/home/oracle7'
    ],
    'cn' => [
      'oracle7'
    ],
    'uidnumber' => [
      '4022'
    ],
    'gecos' => [
      'Oracle7 user account'
    ]
  },
  'uid=oracle,ou=people,dc=fresenius,dc=de' => {
    'gidnumber' => [
      '206'
    ],
    'loginshell' => [
      '/bin/bash'
    ],
    'objectclass' => [
      'shadowAccount',
      'posixAccount',
      'account',
      'top'
    ],
    'uid' => [
      'oracle'
    ],
    'homedirectory' => [
      '/home/oracle'
    ],
    'cn' => [
      'oracle'
    ],
    'uidnumber' => [
      '4267'
    ],
    'gecos' => [
      'oracle db admin'
    ]
  }
};

Note that attribute values in this perl structure are always represented as ARRAY references, even though that most have only single value assigned.
