The db client software is a Managed Code application based on .NET Framework 4.0 which passes credentials to the report utilizing an account that has server-wide administrative privileges.
As far as the database and connection type I listed it above on my first post in this thread but is a SQL Server 2008 R2 vs ODBC (RDO) and according to the SQL Profiler seems to be accessed by the report every time.
Thanks,
