Basically it's simple: To create the users by hand... I can't be changing the web.config each time a user has to login and can't leave mixed mode working as it doesn't pass the right credentials... hey, I want the users loged in by its domain name not NT Authority..

So be it, as what I thought was WRONG - the password inserted in DNN is not the Domain user's password. It can be anything... it will be validated by the domain. So I only need to insert users with his name, surname and username (must be the same as the domain name, like "domain\username".

And a password, you can set it up and forget it... he will use the domain user's one to validate the credentials.

This might sound complicated as I have to create the users by hand... but hey, it's 3 fields only and anyway I would have to set-up their security and roles anyway so it's no major work.

That has worked for me, hope it does for you.

Anyway the AD module should be able to create the users in a future....
