The article direct link User Creds on a URL
Summary
A long while back I posted an entry on linking to a report via a URL. All was good but it only worked if you either:
1. Were hooking BIP up to SSO with your calling application or
2. You placed the report in the Guest folder which was unsecured.
You can now pass the username and password on the URL to avoid the two cases above and open up other possibilities.
