I have helpdesk application which using SQL as a database. I don’t know how to integrating user in my active directory to the application. So, users can log on to helpdesk application with their account in active directory. Why should I integrate active directory user to helpdesk application? Because I have more than 1,400 users. Can anyone help me, how to connect my application using SQL server to active directory(including user password)? Thankyou.
