OData feed permissions

Hello, i have created a report to pull from a web based app. I am using an OData feed as my source. This report is intended for another user and I'm having authentication issues when they try to refresh the data. There are four methods of authentication and im a little confused as to which route to go.  It seems since i created the report the user cannot authenticate with their credentials.  I tried anonymous access as well but received the error below. Given I need to create multiple reports for end users how should i work around this issue? thanks
