In my vb application, the user will login as same as his windows username/password created in the active directory. I also create a separate group and add the users to use the application. Once logged in my application, I want to check the user name and password created for the user in active directory and also whether he is the member of my group.

I had put reference of Active Directory in my vb application and checked the user and group but unable to check the password is correct or not. Can anyone tell how to check the password of a user in active directory is correct or not.

Thanks and regards,

Ramesh Siva
