We have deployed SharePoint 2013 with SQL 2012 Reporting Services in Integrated Mode. When accessing the Web Front Ends directly all reports render as expected.
We published the site behind UAG and we are now seeing an anomaly with Parameters. When you first choose the parameters and generate the report it renders successfully. If you re-run the report with the same set of parameters selected you have about a 60 - 70% chance of success. If you wait 60 seconds and then try you have a 0% chance of success.
The symptom is that the parameters inconsistently fail back to defaults.
The reports are using shared data sources that are populated from sources outside of the SharePoint Farm (Analysis Services or Oracle).
Double hop perhaps (./?)
