What are the alternatives to syncing passwords between AD and CRM in PHP to achieve SSO functionality?

To achieve SSO functionality without syncing passwords between AD and CRM in PHP, you can use a single sign-on solution like OAuth or SAML. These protocols allow users to authenticate once with a central identity provider (such as AD) and then access multiple applications without the need to sync passwords. 

// Example code using OAuth for SSO functionality

// Step 1: Redirect user to OAuth provider for authentication
$oauth_provider_url = 'https://oauth-provider.com/authorize';
$redirect_uri = 'https://your-app.com/callback';
$client_id = 'your_client_id';
$state = bin2hex(random_bytes(16));

$redirect_url = $oauth_provider_url . '?response_type=code&client_id=' . $client_id . '&redirect_uri=' . $redirect_uri . '&state=' . $state;
header('Location: ' . $redirect_url);

// Step 2: Handle callback from OAuth provider
if (isset($_GET['code'])) {
    // Exchange authorization code for access token
    $code = $_GET['code'];
    $token_url = 'https://oauth-provider.com/token';
    $client_secret = 'your_client_secret';

    $data = [
        'grant_type' => 'authorization_code',
        'code' => $code,
        'redirect_uri' => $redirect_uri,
        'client_id' => $client_id,
        'client_secret' => $client_secret
    ];

    $ch = curl_init($token_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

    $response = curl_exec($ch);
    curl_close($ch);

    // Handle access token and user information
    $token_data = json_decode($response, true);
    $access_token = $token_data['access_token'];

    // Use access token to make API requests to CRM or other applications
}
