I've been trying for days now to find a way to get DNN7 to authenticate against our webservice WSDL. I simply want it to use the webservice via SOAP or http post and create the needed cookies once authenticated. IF the user isnt in DNN but authentication is successful it should replicate that user in DNN etc... or otherwise update and sync.

All I can find is really old tutorials for version 3-4 etc... Do I need to create a custom provider? Is ther a recent example of this? Can I just make a module? If I do is there documentation somewhere that shows how to interact with DNN to set the logged in user etc? help!?
