Hello! I need to set a login form from a DNN portal to another. Both are different sites in different installations. What I need, specifically, is that I fill username and password fields in a DNN site (the user doesn't exist in the first portal) and send the data to the other portal, and after being authenticated i need to be redirected to the second portal, logged in.

Is there a way to do this? Maybe through web services or a module providing this functionality? How can I do this? Thanks for the help.
