ldap search returns only one entry

[philosophia]

Is there something wrong with the way I coded this ldap search? It only seems to return one entry ($count=1).

$res = $ldap->search(
    base => "ou=mail aliases,dc=mydomain,dc=com",
    filter =>
      "(&(mailHost=lists.mydomain.com)(owner=username))",
    attrs => [ 'uid', 'mail' ],
);
$res->code() && die $res->error();
$entry = $res->entry(0);
die("Could not look up LDAP entry") if ( !$entry );

@entries = $res->entries;
$count = $res->count;

foreach $entry (@entries) {
    print "dn: " . $entry->dn() . "\n";
    @attrs = $entry->attributes();
    foreach $attr (@attrs) {
        printf( "\t%s: %s\n", $attr, $entry->get_value($attr) );
    }
}

Something seems to be wrong with this ldap search because I know that there are many entries in our directory that match that filter - i.e.,

ldapsearch -b "ou=mail aliases,dc=mydomain,dc=com" -D cn=manager,dc=my
+domain,dc=com -w 'password' "(&(mailHost=lists.mydomain.com)(owner=us
+ername))"

returns many entries.

You don't say which LDAP module you are using. How is $ldap created?

my $ldap = Net::LDAPS->new( $::ldapserver, verify => 'none', async => 0 );
