As of 5/13/2013, it looks like the mechanism that we use to expose a Birst dashboard page to our Salesforce.com users is now causing issues for those Salesforce.com users that do not have a corresponding Birst login.
We currently leverage an embedded Salesforce.com Apex Visualpage on our Account page that is represented as an iframe to provide some key account data to our users. The configuration is the same that is recommended by Birst as seen below in the “Appropriate for an Apex Control within Salesforce” section:
There isn’t any issues for users that have a corresponding Birst login, but for users that do not, we are currently seeing a pop-up error shown above; a recent error. Previously, users were just shown a message stating that they were not an authorized user in the iframe area.
Birst support has been notified, perplexed and then was able to recreate the issue in their environment. Stay tuned folks for further details.
