Re: Unable to bind to active directory using TLS

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; ?>

Here is more information

1. I am binding to Active Directory from Solaris 10
2. My php_info gives configure options as './configure'

'--prefix=/home/local/php-5.2.9' '--with-apxs2=/path/apache2/bin/apxs' '--with-ldap' '--with-ldap-sasl' '--with-openssl=/usr/local/ssl' '--with-mysql=/usr/local/mysql/' '--with-gd' 3. The PATH & LD_LIBRARY_PATH listed via php_info on the browser has exactly the same settings as my user account (that executes the script from command line) 4. I have a ldap.conf file inside /opt/csw/etc/openldap . However this file is not being used by the script (command line or web). I rename the file and nothing changes!. 5. I have apache compiled for mod_ssl

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.

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.

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>
