A new article on SQLServerCentral today: Setting up linked servers with an out-of-process OLEDB provider.

I had to struggle to find the appropriate security settings to make a commercial OLEDB provider work with out-of-process load and I want to share the results of my research with you.

It took 50 hours of Microsoft paid support to partially solve the issue and a huge time spent on Google and MSDN to find a complete resolution. I hope this can help those that will have to face the same issue some day.
