Hi,
When you are using Windows Authentication, then you no need to require to validate password. You can only validate the current user against your database. In your main page (you can check in basepage also), get current user id by using active directory and then query against your table. if the user is exist then allow him to proceed else redirect to access denied/any error message page.

Please let me know if you need still more information.

As I said, AD will return active and valid users only. So no need to password validation required. For application level check, you can validate the logged in user is available in application table.

User.Identity.Name will give the user info (AD) of the logged in user on that operating system.

No need to do a password validation, because always valid AD user can access the system.
