We have an SSRS report embedded in an iframe in Sharepoint. To prevent users from having to enter their login and password each time they access that page in Sharepoint, I need to be able to pass a generic login and password in the URL as not all users have access to the reporting server but all users need to be able to view this particular report. I'm also open to other suggestions on how to accomplish this.
In addition, there are two text boxes with an expression in the Action section that update the report with data for the prior month or next month and those will also need to be modified as they are also making calls to the reporting server.
