We recently upgraded from SQL Server 2008 to 2012, and are now attempting to set the default domain so that when users set up report subscriptions, they can just enterusername instead of username@domain.com.

I'm fairly positive this was previously done in <drive>:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer\RSReportServer.config, and in fact, that location is specified in the official documentation (for 2012) here...

Configure Basic Authentication on the Report Server

The problem is that the file location listed above simply doesn't exist on the server that was upgraded to SQL Server 2012.

When I go to <drive>:\Program Files\Microsoft SQL Server\ I see the following directories:

80
90
100
110

Am I missing something here? It seems as though setting the default domain for SSRS would be pretty straight forward, but I've been working on this all day, and I'm still scratching my head. Any helpful input would be much appreciated.

Cheers,
Tim G.
