We have two asp.net MVC sites which are targeted for .net framework 4.0. One of those is the nopcommerce 2.50.

We have implemented the Single Sign On mechanism for both the sites. It has been working fine. Now if we login to one application the other one detects the user as authenticated.

But we do not know which user is browsing the second application (which is the nopCommerce store). Is there any way to auto login the browsing user on the nopcommerce side?

we have the same username, email, Password, PasswordFormat, PasswordSalt etc in both the databases.

The users can also login to the individual sites using the same username/password. All I need is to make the user auto login to the second application (nopCommerce) if he has already logged in to the first application.

Thanks in advance.
