Active Directory single sign on in asp .net web application

Balaji K

I have active directory installed in the server and my system is registered with active directory. Normally I have logged into the system as an active directory user.

I have a web application (asp .net) hosted in local IIS, web application requires the single sign-on functionality.

Once I have logged into the system as an active directory user, if I access the web application, it should not ask login to user and it should directly navigate to home page.

If the system user not login as a directory user, then the web application should prompt login screen for entering the credentials by the user.

How to implement the active directory user single sign-on functionality in asp .net application

Thanks

Hi Balaji,

1. Configure the application to use forms authentication. This is necessary because this approach relies on cookie based authentication
2. Add the Active Directory connecting string. This element is placed outside the system.web element.
3. Add a membership provider to authenticate against your active directory. Make sure that you provide a username and password which has permissions to access the Active Directory users. In our case, it was the domain administrator username and password. Another important point is that you need to check the correct version of the membership provider present in your installation of .Net framework.
4. Configure the value of machine key manually inside the system.web element. This would be same across all ASP.Net applications that use single sign on.
5. Verify that you are able to login to the application using your Active Directory credentials. You may need to provide the username in the username@domain format.

If the answer is helpful.Then please accept it..!!
