Hello Everyone,

Greetings.

I am unable to bind to active directory using TLS. I get the following error while executing my script via the browser

/*PHP Warning: ldap_start_tls() [<a href='function.ldap-start-tls'>function.ldap-start-tls</a>]: Unable to start TLS: Connect error*/

The same script when executed from the command line works!.

I have compiled PHP with flags --with-ldap --with-ldap-sasl --with-openssl .

Can you help me further trouble shoot this problem?.

Thanks Harish

And what has <?php php_info() ?> to say? I think there might be two .ini files - one for command line and one for httpd php module. So, this one for httpd might be missing: extension=openssl.so extension=ldap.so <whatever is needed>

Should I recompile Apache with mod_ldap or any additional modules - I using a PHP script on my webserver to gather login & password to authenticated against Active Directory?.

Thanks again for your time.

Hello,

I'm sorry, I should have read better. I replied in haste and- Can you please code I've attached? It should be sufficient just to supply credentials. I've tested it and, although I can't make an LDAP connection from console [I've messed something in PHP; ignore], it works for me via WEB [I can see 'OK']. I'm not sure why I've put comments about TLS being buggy [probably something in PHP documentation?], but the code [PHP] works with LDAP TLS just fine.

I don't think you need mod_ldap in Apache, as this one should serve for direct interaction of httpd<-->LDAP [imao].

Let me know, Zdenek

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:

...

If your version was linked against the OpenLDAP libraries, you may want to look at the ldap.conf file for more information about specifying SSL/TLS behavior. Apparently, the settings in ldap.conf make a different in the way SSL/TLS is handled by PHP.

Please, check >> http://marc.info/?l=php-windows&m=116127873321748&w=2
