What are the security implications of using NT-Kennung for user identification in PHP applications?

Using NT-Kennung for user identification in PHP applications can pose security risks as it relies on Windows credentials which may not be secure or easily spoofed. To improve security, it is recommended to use a more secure method of user identification such as session tokens or JWTs. 

// Example of using session tokens for user identification
session_start();

// Generate a unique token for the user
$token = bin2hex(random_bytes(16));

// Store the token in the session
$_SESSION['user_token'] = $token;

// Validate the token on subsequent requests
if ($_SESSION['user_token'] !== $token) {
    // Invalid token, handle accordingly (e.g. log out user)
}
