Re: Unable to bind to active directory using TLS

[Harish Chakravarthy <harishvc@gmail.com>]

Hello Everyone,

Below is my Php test script (minor modifications to Zdenek's script) . This test script works from command line but not from the web. "TLS connect failed!" is my error message when I execute the script via web. Any assistance is welcome.

Also my environment is Php using  OpenLDAP on Solaris 10 connecting to Active Directory.

<?php
define('MYLDAP_HOST', 'ldap://my.server');
define('MYLDAP_PORT', 389);
define('MYLDAP_BINDDN', 'CN=something,OU=Users,OU=Administration,DC=edu');
define('MYLDAP_PSWD', 'something);

# Required for working via command line
putenv('LDAPTLS_REQCERT=never') or die('Failed to setup the env');

$ldapConn = ldap_connect(MYLDAP_HOST, MYLDAP_PORT);
if (!$ldapConn) {
       exit("Unable to connect to LDAP server");
}
if (!ldap_set_option($ldapConn, LDAP_OPT_PROTOCOL_VERSION, 3)) {
       exit("Unable to set protocol version to v3");
}
$tls = ldap_start_tls($ldapConn);
if (!$tls) { exit("TLS connect failed!"); }
$ldapBind = ldap_bind($ldapConn, MYLDAP_BINDDN, MYLDAP_PSWD);
if (!$ldapBind) {
       exit("LDAP Bind failed");
}

echo "Works!<br/>";

ldap_unbind($ldapConn);

return 0;
?>

Also, does TLS work with LDAP itself?
There is also comment at php.net which says:
