Thanks for your prompt responce. We figured that much out. Here's what we are trying to do: incorporate the RPXNow provider with DR/DL for simplifying new registrations via facebook, yahoo, etc. We currently have the cirrius module installed and working with DR - and we're hoping the new DL authentication provider would help us customize the login procedure.
The problem is that the return url (after authentication) seems to be handled by DNN. See image below. Essentially, we want to bypass this step all together - and go directly to DR - with all fields pre-populated. Currently, the user must read through this stuff, and then click the little 'register' link first. This is very tedius and confusing to most new users.
Ideally, the "Associate with Existing Account?" question should be in fine print on the top of the DR form. However, we would be just as happy bypassing this step entirely (it's a new portal).
Can you help us with this?
