Set up DUO Mobile A2F in PHP with LDAP authentification [closed]

I need to protect a PHP web application with double authentication using DUO Mobile.

Here’s how I’d like it to work for a user wishing to access the application:

1. User enters Active Directory login and password
2. The application asks the user to perform double authentication
3. A push notification arrives on the user’s phone.
4. He confirms the connection
5. The application grants access to the user.

Is this possible, and if so, how should I proceed?
