How to Use PHP LDAP on Zimbra

[peter76]

Can someone please help me? I don't know what I'm missing.

ldapsearch works just fine:

ldapsearch -x -v -H 'ldap://hostname' -D 'uid=zimbra,cn=admins,cn=zimbra' -b "dc=com" "zimbraMailForwardingAddress=user@domain" mail -W | less

I'm doing this in php:

$c = ldap_connect("hostname") or die("Peter cannot connect to LDAP server.");
ldap_set_option($c, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($c, LDAP_OPT_REFERRALS, 0);
ldap_start_tls($c);
$bind = ldap_bind($c, $user, $pass);

But I keep getting this error:

Mar 12 16:01:36 localhost httpd: PHP Warning:  ldap_start_tls() [<a href='function.ldap-start-tls'>function.ldap-start-tls</a>]: Unable to start TLS: Connect error in /var/www/html/ldap.php on line 14
Mar 12 16:01:37 localhost httpd: PHP Warning:  ldap_bind() [<a href='function.ldap-bind'>function.ldap-bind</a>]: Unable to bind to server: Can't contact LDAP server in /var/www/html/ldap.php on line 15

This is in /etc/openldap/ldap.conf:

TLS_CACERT      /etc/openldap/cacerts/ca.cer

What am I missing? I've been banging my head against this brick wall for days. Thank you.

Hi Peter
Here is PHP script to bind with Zimbra LDAP Server. Hope it will help you.
################################################
<?php
$ldap['pass'] = 'password';
$ldap['host'] = 'zimbra-ldap.example.com'; //or you can put IP of ldap server
$ldap['port'] = 389;
$ldap['dn'] = 'uid=zimbra,cn=admins,cn=zimbra';
// connecting to ldap
$ldap['conn'] = ldap_connect( $ldap['host'], $ldap['port'] );
ldap_set_option($ldap['conn'], LDAP_OPT_PROTOCOL_VERSION, 3);
// binding to ldap
$ldap['bind'] = ldap_bind( $ldap['conn'], $ldap['dn'], $ldap['pass'] );
if ($ldap['bind']) {
echo "LDAP bind successful...";
} else {
echo "LDAP bind failed...";
}
?>
