I have seen some discussion about single sign on but it is from the perspective of using DNN as the front end to do single sign on into another application.
We have an existing .NET application that already has a membership with authentication (not AD). We were asked to create an easy to maintain community site for the membership that uses this application. So we created a DNN site. Now, after the fact, we were told that we need to authenticate users on the main site and pass in their credentials on the DNN site. So I am trying to determine the entire scope of doing this and the best approach.
First, it seems like we will need to create a DNN user for every existing user on the main app. I know there are DNN modules that I can use to auto create the existing users from a spreadsheet. Is there a better way?
Second, it seems like for every new user on the main site we will need to create a DNN user. What are the best methods for doing that?
Third, we need the ability to authenticate from the main site into the DNN site.
Am I missing anything on the scope? Any ideas or examples would be much appreciated.
