Description:
------------
Hello,

I've written a patch against PHP-5.0.2 that properly impelments LDAP SASL binds for all mechanisms.  The current code in 5.0.2 does not support LDAP SASL binds at all, although the function exists.

The patch can be found at:

http://www.stanford.edu/services/directory/clients/examples/ldap-sasl

It follows the PHP development guidelines.

This patch has been tested with multiple SASL authentication mechanisms.

Regards,
Quanah

Reproduce code:
---------------
#!/usr/local/bin/php
<?php
$ldap = ldap_connect("ldap.stanford.edu");
if($ldap) {
   $r = ldap_bind($ldap);
} else {
  echo "Unable to connect!";
}

ldap_set_option($ldap,LDAP_OPT_PROTOCOL_VERSION,3);

if (ldap_sasl_bind($ldap,"","","GSSAPI"))
{
    $dn = "cn=people,dc=stanford,dc=edu";
    $filter = "(|(susearchid=$WEBAUTH_USER)(mail=$WEBAUTH_USER@*))";
    $result = ldap_search($ldap, $dn, $filter);
   
    if ($result)
    {
       echo "Number of entries returned is " . ldap_count_entries($ldap, $result) . "<br />";
       print("\n");
       $info = ldap_get_entries($ldap,$result);
       echo "Data for " . $info["count"] . " items returned:<p>";
       print("\n");
       
       for($i=0;$i<$info["count"];$i++) {
           echo "dn is: " . $info[$i]["dn"] . "<br />";
           print("\n");
           echo "first cn entry is: " . $info[$i]["cn"][0] . "<br />";
           print("\n");
           echo "first email is: " . $info[$i]["mail"][0] . "<br /> <hr />";
           print("\n");
       }
    }
       
ldap_close($ldap);
}
?>

Expected result:
----------------
I'd expect this to work in PHP

Actual result:
--------------
Doesn't work at all without my patch.

Works correctly with my patch.
