Dotaz: Autentizace uzivatelu webu pomoci kerberos

[OgeeN]

Ahoj,
potrebuji zprovoznit autentizaci pristupu uzivatelu nasich webovych pomoci pam modulu kerberos.
Na nasich strankach pouzivam redakcni system phpwebsite a ten nabizi pro externi autentizaci tento skript:

cat external_authorization.php
/*
* Function to use the VMS authorization technique in
* lue of an honest LDAP connection
*
* @param username : string with username
* @param password : string with password
* @return String with authorized user type FACULTY/STAFF as example
* OR returns false if error or unauthorized.
*
* This is an example of external authorization. Basically you just
* need an 'authorize' function that accepts an username and password.
* It will return TRUE or FALSE.
*
* You can also add a processUser function. It accepts a pointer
* to the user object. It will only be called if an externally authorized
* user is not in the local system.
*/

function authorize($username, $password) {
$address = null;
$port = null;
$data = null;

if(empty($password) || (strlen($password) == 0)) {
return FALSE;
}
if(!($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP))) {
return FALSE;
}

if(!socket_connect($socket, $address, $port)) {
return FALSE;
}
if(!socket_write($socket, $username."/".$password."\r\n")) {
return FALSE;
}

while(($buf = socket_read($socket, 512)) !== false && ($buf!=""))
{
$data .= $buf;
}


if ($data == "INVALID")
return FALSE;
elseif (preg_match("/ok/i", $data))
return TRUE;

return FALSE;
}

function processUser(&$user){
$user->email = $user->username . "@emaildomain.com";
}

?>

Rad bych proto pozadal o radu jak bych mel tento skript upravit tak, aby pri pokusu o autentizaci zavolal modul pam_krb5.so a ten vratil TRUE nebo FALSE.
Samotnou autentizacaci vuci kerberu uz rozbehanou mam, jen ted nevim jak primet muj redakcni system, aby ji pouzival.
Diky za radu.

Na otázku zatím nikdo bohužel neodpověděl.
