I am very new to DNN.  We have a DNN website.  We have a client that will have a button on their site, that when one of their users clicks on it, it will send them our site and they will pass the user's name.  We need to capture that name, derive a username/password from this, give it to the signin.ascx for validation against the DNN membershipd database.  The end user will never see the signin.ascx page.  If they are not validated they will see another page that they need to contact their administrator for access.  We don't have to go to the signin.ascx page, but still need the functionality of validation and redirection to the correct page if they pass.  Currently their user info will be passed as a query string later to be replaced by something more secure, but this is an immediate need.

I have read several posts that talk about not being able to use query strings, but really didn't find any help on what to do if we need to get that data to the default.aspx page as described above.

If anyone can send me the code or post it here, it is greatly appreciated.  I am behind on this project because of this one hold up.

Thanks

Cynthia
