How do I set up Active Directory authentication for a specific application?

Install and configure the Active Directory (AD) server roles.
You will need to add two new roles to your AD: an AD domain controller and an AD federation services server.
Configure the AD security policies.
You will need to adjust policies such as password length, complexity, and expiration, in addition to account lockout settings.
Design a single sign-on (SSO) flow.
When users login to your application they must have access to their AD credentials. This means designing a seamless, secure SSO flow so the user can access the application without having to input their credentials again.
Test the authentication using the AD server.
This will involve configuring the application to use AD credentials, ensuring that authentication is working correctly, and testing the SSO flow.
Enable multi-factor authentication (MFA).
To ensure a secure and compliant environment, you should enable MFA for enhanced security.
Monitor access logs and audit user activity.
To ensure that the AD server is constantly monitored, you should consider using log monitoring and auditing tools that will notify you if there are any suspicious activities or access attempts.
