Discovered a great tool that is very helpful for testing security. It lets you open any program under a different user account just like "Run as... " in Windows.
Ex: I want to test if my security works correctly in Excel for users in specific roles - I would copy my Shellrunas.exe into C:\Program Files (x86)\Microsoft Office\Office12
Then go to command prompt and run
cd C:\Program Files (x86)\Microsoft Office\Office12
C:\Program Files (x86)\Microsoft Office\Office12>shellrunas excel.exe
This tool has helped me a lot, because the native Windows "Run as..." functionality that could be achieved by holding Shift down and then right click didn't work on my Windows Vista for Excel and "Run as..." is not available for SSMS and for IE as well.
This tool helps work around this limitation:
