I have code in a custom module that checks if the session variables are not set and if so requires a user to login to the system again. We are performing additional login requirements that are handled first and then if all pass we log the user into the portal using the DNN login process

UserController.UserLogin(PortalId, objUserInfo2, PortalSettings.PortalName, Request.UserHostAddress, True)

now there is also code that determine the session variables are missing and then sends the user back to login. the problem is they are logged out of custom DB but not the DNN Portal:

            If Session("userBureauID") Is Nothing Or Session("userCompanyID") Is Nothing Then

                Response.Redirect(Globals.NavigateURL(loginPage) & "?timeOut=" & "true", True)

                ' log out of DNN???

            End If

I am still trying to find a way to logout of the DNN session. This method does not work nor do any others I have found, seems odd to me that there is no simple way to force a log out in DNN. Any help please
