Hi Sadegh,

Good question, but it's hard to answer because I'm not familiar with all your requirements. On the diagram from my previous post I was assuming that users are already in AD, and additional users will be created directly in AD. To be honest I wasn't thinking about the registration.

To implement registration feature, a DNN plugin can be created. DNN will expose HTML form that in backed will create an user in AD 'user store'. I think, one registration entry point is enough.

A1: Users will login to "A". For example, when user will navigate to DNN website, he will enter his AD credentials into the DNN login form. In this case user will not be aware of AD 'user store', whole sign-in process will be within DNN.

A2: There is no official DNN plugin that allows register/create AD user from DNN. We 'Glanton Corp' have non official DNN extensions that can do that. We just need to know your requirements to suit 'self-registration' module for you.
