How do I implement CAS in my code?

To implement CAS (Central Authentication Service) in your code, you need to follow these steps: 1. Set up a CAS server, 2. Integrate the CAS client library in your application, 3. Configure your application to use CAS for authentication.

What programming languages support CAS?

CAS can be implemented in various programming languages, including Java, Python, PHP, and Ruby. Most languages have libraries that facilitate CAS integration.

Can you provide a code example for a Java application?

Sure! Here's a simple example in Java:

import org.jasig.cas.client.authentication.AuthenticationFilter;
import org.jasig.cas.client.validation.Cas20ServiceTicketValidator;

public class MyApp {
    public static void main(String[] args) {
        // Initialize CAS client
        AuthenticationFilter filter = new AuthenticationFilter();
        // Your CAS server URL
        String casServerUrl = "https://your-cas-server.com/cas";
        // Set up the ticket validator
        Cas20ServiceTicketValidator validator = new Cas20ServiceTicketValidator(casServerUrl);
    }
}

What are the common issues when implementing CAS?

Common issues include misconfiguration of the CAS server, SSL certificate problems, and session management issues. It's important to check logs for errors.
