I hope that someone can help me.  I am using DNN to build a replacement for my company's intranet, and until I finish developing the rest of the modules that are needed, I need to provide access to the users to a helpdesk module that I wrote.  There is currently a link to a current helpdesk system from our intranet, and I would like to change that link to point to the new DNN portal directly to the new module.

Is there a way to "pass" the login information from the previous ASP application to the portal to automatically log them in to the portal either through a query string or some other medthod so that they can just click on the existing link and get directly to the helpdesk on the new portal without having to login to this system as well.

Thank you for any help with this.  I appreciate it.

The code to log a user into DotNetNuke is simple:

 'Log the user in           
Dim objUserInfo As UserInfo = UserController.GetUserByName(PortalId, strUserName)           
UserController.UserLogin(PortalId, objUserInfo, PortalSettings.PortalName, Request.UserHostAddress, True)

Here is some code that might help:
