Code snippet demonstrating how to establish a TLS-encrypted connection to an OpenLDAP server from an Apache webserver and authenticate using a user's Kerberos credentials. Credentials MUST be delegated to the web server for this method to work.





<?php





putenv("KRB5CCNAME={$_SERVER['KRB5CCNAME']}");





$resource = ldap_connect("ldap.example.com")


    or die("Failed to connect to LDAP server.");





echo "Connected to LDAP server.<br />";





//these options may not be necessary in all environments


ldap_set_option($resource, LDAP_OPT_PROTOCOL_VERSION, 3);    


ldap_set_option($resource, LDAP_OPT_REFERRALS, 0);


    


$result = ldap_start_tls($resource)


    or die("Failed to start TLS");





echo "Started TLS.<br />";





$result = ldap_sasl_bind($resource, NULL, '', 'GSSAPI', 'EXAMPLE.COM', '', '')


    or die("Failed to GSSAPI bind.<br />");





echo "GSSAPI bound.";


   


?>

With the patch introduced in the bug below (which has been included in CVS), the parameters for this function should be:



bool ldap_sasl_bind ( resource $link [, string $binddn [, string $password [, string $sasl_mech [, string $sasl_realm [, string $sasl_authc_id [, string $sasl_authz_id [, string $props]]]]]]] )



Some example calls:



$r=ldap_sasl_bind ( $ds, NULL, 'mysecret', 'DIGEST-MD5', NULL, 'jimmy');



With authz_id, specifying a dn:

$r=ldap_sasl_bind ( $ds, NULL, 'mysecret', 'DIGEST-MD5', NULL, 'jimmy', 'dn:uid=tommy,ou=people,dc=example,dc=com');



With authz_id, specifying a SASL username:

$r=ldap_sasl_bind ( $ds, NULL, 'mysecret', 'DIGEST-MD5', NULL, 'jimmy', 'u:tommy');



Also, since SASL authentication was introduced in LDAP version 3,

you may need to explicitly set the version number with:

ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
